The Bycan HU-21 power adapter gives 200 amps of power when hooked with two of our PS-28100 units. This gives you the power needed when running VCS, avionics, and performing gear retractions in most piston and turbine aircraft. By far the most affordable solution on the market.

The HU-21 includes an 8-foot DC line with power connector and APU plug, which gives you a total of 24 feet of extended power from AC source when two of the PS-28100’s are connected in to the unit.
