Overview
|
The D B Assembly, Inc P-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 P-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 selected by a front panel switch. The charging process is fully automatic. When the charge is in progress a red LED is illuminated. This is replaced by a green LED when the aircraft battery is fully charged. The ON/OFF switch on the unit also resets the unit. The 14-volt version, P-1450 provides 50 amperes of filtered DC at 14 volts. Note: P-2850A / P-2850 APU units leave the factory at 30.3 volts with no load. 95% of general aviation aircraft have the ability to automatically drop the voltaege to the required voltage, depending on the amount of load applied to the APU. If an aircraft is one of the few which cannot automatically drop the voltage, an additional resistor kit, RK3X15, will need to be purchased separately. |
