MFR Model# PS-2850


The Bycan PS-2850 Aircraft Ramp Power Supply and Battery Charger is a dual-purpose aircraft flight line service and maintenance tool. The unit has a filtered 28-volt DC power supply with up to 50 amperes capability for tests of aircraft electrical systems and a secondary mode for recharging run-down batteries.

This ramp or hangar accessory is an absolute must for avionics service, gear and flap actuator exercising and other electrical system service.

The PS-2850 plugs directly into the aircraft APU connector and is tied to the electrical system when the master switch is activated.

The battery charging mode is selectable by a front panel switch. The charging process is fully automatic. When the charge is in progress a red LED is illuminated. A green LED replaces this when the aircraft battery is fully charged. The on/off switch on the unit also resets the unit.

I purchased this power system to cycle my aircraft landing gear after doing maintenance/annual. It works perfect. Aircraft Spruce did a price match since I found it a little cheaper else where. Hopefully it will continue to operate flawlessly for many years to come. Ill write another review after my next annual.
