The model 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.

Whelen deal'n for a new power supply......AgainBy Winn from Dallas, Texas on April 27, 2011 I have owned three of these units and all have failed. Total aircraft time around 1000 hours of which approximately 35% of the hours flown were at night. I did not use the strobes during the day. So, 3 strobe power supplies have lasted 350 hours or about 116 hours of operation each. I don't know if that is normal or not, but it sure is expensive.Pros:When the supply works, the strobes flash wonderfully.Cons:High cost and short lifespan.Whelen A413AHDACF Power Supply - 01-0770028-05 Your question might already be answered below, wouldn't that be a time saver!
