HDACF series provides simultaneous flashing, alternate flashing or both. It will operate one, two or three strobe lightheads. Operating the wing tip strobes in the alternating mode will provide an accumulated 42 joules of power to each light. When in the simultaneous mode, the accumulated power to each light is 21 joules. In the three light mode, the wing tips will flash simultaneous at an accumulated 21 joules each, they alternate with a third light operating at an accumulated 42 joules. On the trigger selector outlet, a switch mounted in place of the jumper will allow wing tip outlets 2 & 3 to be turned off, while the tail outlet 1 will remain on. This function is commonly used when the third light is for ground operations. This power supply will operate from 10 to 30 VDC.
Model No. 01-0770028-05
Works well. Got 10+ years and 1,450 hours out of last one. I could complain about the price too, but they got you grabbing your ankles in anything aviation. Gotta buy another one. Pass the grease.
Works great, but apparently made of gold and platinum. $674.00 to make your strobes flash-aviation for the little guy must die.
There is no difference since they are the same part. The Whelen model number for our part number 11-16218 is 01-0770028-05
Per the supplier: Any 2 outputs can be used depending how you want them to flash.
Per the supplier: Yes, it is the same and is backwards compatible.
Per whelen, it will work fine with older strobes.
