Overview

The B-14/2850 plugs directly into the aircraft APU connector and is tied to the electrical system when the master switch is activated. Selection of output voltage is by a front panel switch which is protected by a switch guard. Closing the guard forces the switch to the 14 volt position.

The P-1450 series plugs directly into the aircraft APU connector and is tied to the electrical system when the master switch is activated.

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

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. 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.

Specifications

  • On the charging feature, the output current that is optimum should be equal to 10% of the battery ampere hour rating.


  • The AC current drain during maximum current (Fully Discharged Battery) can be computed using the following formula:

  • I ac = V battery x I dc current x 1.5 / VAC

  • This shows that batteries that require a high charging current should be charged with 208/220 or 240 VAC input to the charger rather than 115 VAC
