Most of them are in the trash where this unit belongs. Switch to led :)

Agree completely. And the goods new is the changeover is easy. Hardest part is taking out some flooring to get at the power supply. So remove the power supply. There are five wires going out to the wingtip with the old Whelen nav/strobes. You only need 4 for the LEDs and that includes the sync wire. Splice the wires under the floor in the appropriate manner (it's not hard, after all, I did it). Your done, you don't even need to change any switches.
 
Agree with others, LED technology has overtaken xenon flash tubes, at lower cost. But if you want to look inside, remember those capacitors can store high voltages for some time. Don’t assume anything, carefully discharge (use an insulated ground wire) the capacitors before anything else.

Thanks Walt.
I'm afraid it will be a little problem to "stop by", since I live in Israel....
Thanks again.

Good Morning Ariel.

It looks like flyled makes a module to match the footprint of that power supply:

Products – Flyleds

flyleds.com flyleds.com

It lets you switch over to their LED kit without having change very much at all.
That said, if the unit is non-functional at this point and you really want to fix it you may as well crack it open. The circuitry looks very straight forward so even without a schematic this should be easy to debug (says the person several thousand km’s away). This may be as simple as a diode from the power supply side having got cooked. Start by looking for obvious darkness on the PCB.

Good luck.
 
I’ve still got the power supply and lights but swapped it out for WAT’s LED Orion replacements. As stated, it’s not hard but you do need to properly join the existing wires together. I did this last year and very happy. I did upgrade the strobe switch to a 15A breaker. IIRC should all 3 flash at the exact same time I think it could require slightly more than the 10A the previous switch provided. The wings are sync’d and the tail does its own thing. The bus bar made it really easy to splice it all together.IMG_2009.jpeg

Hi. Does anyone of you have the internal schematic of the Whelen Strobe Lights Power supply Model HDACF?
Thanks,

The most common failure is the (large) electrolytic storage capacitors. Particularly if the power supply has sat un-powered for a significant period (many weeks). They are easy to identify and test when you open the case. Replacements are widely available (e.g. DigiKey).

There may also be a fuse inside the case. Start at the input connector and trace inwards to the power section and you may find (and test it).

If it’s neither of these, test the high voltage output (carefully! With an appropriate meter). If it’s up above 400v and your strobes won’t fire the failure is probably the power MosFET in the trigger section.

Hope this helps, unfortunately I was never able to find a published schematic or repair manual. Cheap (used) replacements are common on eBay.

Good luck.

Thank you!
It seems to be the same.
If I'll not be able to fix mine (Which more interesting me than buying a new one....), I'll buy theirs.

Hi Ariel.

Just so you are clear on what this is. It is NOT a replacement for the whelen strobe power supply. Its a power supply for their LED strobe that drops into the same footprint as the whelen power supply. It’s meant to make it easier to swap over to LEDs.

Cheers.
