    Default Pre-Order JM-PhD-X1, PWM Lantern Regulator

    JM-PhD-X1
    Pre-Order is now OVER
    THE SALE IS ON.
    I'm pleased to announce the sale of the JM-PhD-X1. This regulator design is primarily for those of us with SERIOUS power regulation requirements. The folks that build lantern style lights using 600W+ aircraft lights.
    Here is a picture of the PCB design. I will replace it with a picture of the actual regulator once they're built.



    This is another regulator design based on my previous PhD-D1 and the work linked to below.
    This has been built based on my previous JM-PhD-D1 found HERE.

    The feeler thread for the PhD-X1 can be found HERE. This discussion is an evolution. Many many options were discussed, but it was whittled down to something more simple and robust rather than something super feature laden and expensive.

    How it works: It uses PWM (Pulse Width Modulation) to control the RMS voltage to the bulb. By turning a switch (an FET) on and off several times (244Hz) a second, the "effective" voltage that the bulb sees can be controlled. The bulb is still receiving the full battery pack voltage while the switch is on, but it’s not on for the whole time. The frequency of the PWM and thermal mass of the filament prevent flicker. It can only control output voltage less than or equal to the pack voltage. It cannot boost battery voltage.

    Hardware:
    -Dimensions: 69.6mm x 55.5mm (2.75 IN x 2.19 IN)
    -The "Drive Section" can, at the user's option, be separated from the "Control Section" by the user to allow remote mounting of the high current components.
    -Voltage input range is 17V to 70V.
    -Current carrying capability: Projected Minimum 40A RMS.
    -Dual 3.9mOhm FETs with Heatsinks (WARNING: The heatsinks are electrically connected to the "Bulb" connection on the regulator board)
    -High current connections: Mounting holes for ring terminals (#8 screw) or soldering.
    -Auxiliary PWM outputs for future use of warning LEDs or FANs. Enabled by custom programming.
    -Auxiliary power connections allow up to 400mA at ~11.4V to drive outboard electronics. amp/volt displays, fans, LEDs, etc.
    -Solder pads for the control button (button not included).
    -2 Auxiliary micro-controller pads that can be enabled for other functions with custom programming.
    -Removable/replaceable micro-controller (Atmel ATTiny84).
    -1 dual switch DIP switch for future use with custom programming.
    -FET drive disable jumper. This is used to disable the output during programming. If the regulator is programmed while the jumper is in place, it could blow the bulb.
    -There are no user adjustable pots on the board. ALL changes must be made in software and programmed into the board.

    -------- BEGIN WARNINGS----------
    This regulator can work with voltages in excess of 48V (70V maximum). These voltages can be dangerous. The user/purchaser accepts FULL responsibility that all proper safety precautions are taken. If you're not familiar with working with these voltages, please do not experiment with this regulator.

    The heatsinks on these regulators are electrically connected to the "BULB" connection on the PCB and can carry the full battery voltage at times. If the heatsink(s) is/are shorted to ground, the bulb will receive the full battery voltage and may be damaged or explode. If the heatsink(s) is/are shorted to other components on the board, it will destroy the board, possibly beyond repair. It is up to the user to ensure that the regulator is mounted in such a fashion as to allow electrical isolation if the heatsinks.

    The bottom of the regulator board has connections that carry the full battery voltage. These must NOT be allowed to touch anything electrically conductive or a short circuit may be caused potentially destroying the regulator and/or causing a fire.

    Parasitic current ("Off mode" current). While the regulator is shut off, it will still drain a little current from your batteries. It's about 3mA.

    Bulb Disable Jumper: You MUST remove this jumper if you are programming this regulator while it is installed in the light. You could cause bulb damage if you program the regulator with this jumper in place.

    -------- END WARNINGS----------

    Software Options:
    Currently, the software is written to allow the below options.

    -Multi-level, single button interface. 1 push turns the light on to the first level or the last level used (See config options). Up to 5 levels can be specified in the configuration. Pressing and holding the button for about 1 seconds will shut down the regulator.

    -Memory Start: If used, the regulator will start to the level that was last in use when it was shut off.

    -Low voltage warning: At a programmed voltage (selected at purchase) the bulb can either pulse or dim to indicate a low battery voltage condition exists.

    -Low voltage shutdown. At a user selected percentage of the Low Voltage Warning, the regulator can shutdown. In addition to this, the user can select a time (in seconds) the the low voltage warning can be active before the regulator shuts down.

    -Over Temperature warning/shutdown: This is here to protect the electronics. This feature is not intended to protect your bulb, wires, battery, or lantern body. If activated (at 80 deg C), it will dim the bulb to 35% of the active voltage level. It will stay there for up to 30 seconds. If the regulator is still above 80C after 30 seconds the regulator will shut down.

    -Soft start: 3 user selectable softstart options are available. Slow, Medium, and Fast. Slow is good to use if you are really over driving your bulb and want to be as gentle as possible. Medium is a good selection for most users. Fast will start the bulb in about 100mS.

    Softstart: Slow, Med, Fast
    Low Volt Warning: Pulsing or Dimming


    Customized programming: At this time I cannot offer extensive custom programming. This includes incorporation of onboard hardware (auxiliary uC ports, thermal sensors, PWM outputs, DIP switch for selectable options, etc).
    If you want your regulator reprogrammed with new voltages and are unfamiliar or uncomfortable doing it yourself, I will accommodate you for free. You will pay return shipping. That being said, I may offer additional functionality in the future with new firmware. These new releases are free and I'll reprogram/upgrade your regulator for you or send you the newer code if you want to do it yourself. Again, you will pay return shipping. However, if the regulator is somehow defective or otherwise "misbehaving", I will work with you to make it right and I will cover return shipping.

    Connection diagrams, instructions, and firmware can be found here:
    http://mysite.verizon.net/jminihane/id2.html

    Ordering/Shipping information:
    Currently, I am unable to get all the parts necessary to build these (1 part on backorder until January 2011). I have ordered all the parts necessary. So I'd like to offer a pre-order/pre-pay sale on these regulators.

    Pricing:
    Regulators:
    Effective now, each regulator will cost $80.00 USD
    Shipping:
    These regulators are larger than the PhD-D1 and cannot be shipped via padded envelope. I will ship them via USPS (US Postal Service) Flat Rate Box.
    United States: $6.00 USD
    Mexico/Canada: $12.00 USD
    All others: $15 USD
    You will only be charged for shipping once per order. I imagine I could fit 6 or so regulators in a box. Maybe more.
    PayPal Fees: (Fees apply to entire amount sent. Regulators and shipping combined)
    Credit Card PayPal transfers, please add 3%.
    Non-US purchases, please add %4
    If Credit Card AND Non-US purchases, please add 7%

    Only 25 of these will be made.

    Regulators will be programmed and shipped as soon as the last part is installed. All regulators will be shipped with the most current firmware.



    Payment for Orders is being accepted NOW.
    I only accept PayPal payments. Please send PayPals to j.minihane@yahoo.com

    Revision 2 of the firmware has been released with new features and a small improvement here and there.
    *** WARNING ***
    You MUST use a Rev 2 options file with this release. You CANNOT use your Rev 1 options file.

    Rev 2a - All functionality found in Rev1 Plus...
    - Low Voltage Latch mode that hold the low voltage waning mode even if the battery recovers. This can prevent a heavyily loaded pack from "fooling" the low voltage sensing and causing the light to appear to blink.
    - Additional Over Temp warning (OT_TYPE = 2). Shuts down the bulb and uses the Auxilliary PWMB Output to drive the ground leg of an LED as a flashing Warning.
    - Additional Low Voltage warning (LV_TYPE = 3). Shuts down the bulb and uses the Auxilliary PWMA Output to drive the ground leg of an LED as a steady Warning.
    - Configurable duty cycle of PWM A & B Outputs when used as Overtemp or Low Voltage warnings.
    - A Mode to allow the Aux PWM A output to control a relay that completely disconnects the regulator power supply. Wiring details can be found in my web site above.
    - In Rev1, when the main output was shut down due to overtemp/low voltage the output was actually reduced to 1/4095th duty, not truly off, before it was completely shutdown ~4mS later and the regulator was put to sleep. This also occurred between the time you held in the button to shut it down and releasing the button. Now the output is reduced to zero output during these short time periods. Don't worry. When you shut down your regulator with Rev1 it is actually shut down. It just went into an almost 0 duty cycle for a short period beforehand.

    Here are the new programming options that you should cut and paste into your order.

    Bold items are default settings.
    Please cut and paste this into your post and edit the voltages/options you desire for each setting.
    Leaving a voltage as 0.0V will mean that level is not enabled.
    Level-1: 0.0V
    Level-2: 0.0V
    Level-3: 0.0V
    Level-4: 0.0V
    Level-5: 0.0V
    Memory Start: (Yes/No)
    Soft Start: (SLOW/MED/FAST)
    Vlow: 0.0V (The voltage where the low voltage warning should kick in.)
    Vlow Warning Type: (Pulsing/Dimming/Shutdown Output & Flash PWMA Output)(PWM Duty % when on)
    Vlow voltage based shutdown: Percent of Vlow (94%)(Enabled/Disabled)
    Vlow timed shutdown: Seconds before shutdown (30 Seconds)(Enabled/Disabled)
    Vlow Latch: (Enable/Disable)
    Over Temp Warning Type: (Dimming/Shutdown Output & Flash PWMB Output)(PWM Duty % when on)
    Relay Disconnect: (Enable/Disable)

    Note: You cannot combine the Relay Disconnect option with the PWM A/B options for Low Voltage and Temperature warnings.

    Yes. PayPal now to get the pre-order pricing @ $100 each.
    In any case, I'll be contacting all pre-order customers for confirmation of their configuration settings.
    Thanks, Starlight.

    I believe they were 4559x. Is there anything more focused is that output range that I can run off a 30ish volt battery? (it's a 10 cell dewalt pack)

    Not that I'm aware of. The problem is the reflector. It's not very deep.

    Many parts have already shipped. Still waiting on a few on back order. The onboard regulator that I was going to have to wait until January for has already shipped. But have to wait a few more weeks for the FETs. I should have the majority of the parts next week or the week after.

    I've just received most of the parts (including the ones scheduled to ship in January). I'm waiting on the FETs, Digikey was low on stock and they'll arrive in November. I ordered the boards last night, they'll take about a week.
    Once everything arrives, I'll give another update.
    Christmas may come early.

    Got it.
    But you don't need to specify Vbulb(max) or other percentages any more.
    The voltages are set directly as voltage numbers out to tenths of a volt.
    Also, disabling the overtemp shutdown is NOT an option. If the regulator exceeds 80C it could potentially be damaged.
    In testing, the Vout was amazingly close to the programmed values. Usually < 0.01V deviation as Vbat was varied.
    Mmmmm... 12-bit regulation.

    Here are the settings I will use...
    NEW X1 REGULATOR #1 for 64663 bulb
    Level-1: 20.0V
    Level-2: 27.0V
    Level-3: 32.0V
    Level-4: 39.0V
    Level-5: 0.0V
    Memory Start: YES
    Soft Start: MED
    Vlow: 40.0V
    Vlow voltage based shutdown: YES 94%
    Vlow timed shutdown: DISABLED

    ------------------------------------------
    NEW X1 REGULATOR #2, and #3 for 4559 bulb
    Level-1: 15.0V
    Level-2: 20.0V
    Level-3: 24.0V
    Level-4: 29.5V
    Level-5: 0.0V
    Memory Start: YES
    Soft Start: MED
    Vlow: 37.0V
    Vlow voltage based shutdown: YES 94%

    Boards have shipped and the paste stencil will ship very shortly.
    I have enough FETs on hand for 6 units. The remainder are still on backorder with Digikey.
    Initial testing will be done with only one FET in place, farthest away from the terminals. Then I'll use my power supply to run 3 64458 or 64623 bulbs in parallel for a 20+ amp load. Even with the 20A limit on my power supply, I should be able to get >20A RMS at the bulbs since I have a big capacitor on the power supply output and the regulator uses PWM. If one FET can do 20A, then 2 will do 40A. I can't afford to buy a big enough power supply to test these things at full power.
    Once testing has concluded and I'm satisfied with the power handling, I'll post a pre-order end date.

    Well,
    Welcome back everyone. Due to the recent crash, we've lost a bunch of good posts.
    But here's where things stand.
    All orders have been received and shipped as necessary.
    I have built a little website for keeping support files.
    http://mysite.verizon.net/jminihane/id2.html You can find instructions, calibration factors, diagrams, etc there.

    Well, After these are sold (another 12), I will be researching the possibility if a C regulator. Depending on how well that goes, I'll be either building that or another run of the D1s.
    I've been kicking around an idea for a D2, but that's still just an idea.

    I'd be up for a Ds or Cs. So how would a D2 be different than a D1?

    SN001 is tested and working perfectly. I am currently trying to mount the bulb socket in a Big Beam reflector. SN002 is installed in a new Larry12K. It also works perfectly. SN003 is waiting on a new host. These are VERY nice, Jimmy. Thank you.
