MFR Model# R15V00-A


The R15V00 Rev A is a 14Vdc electronic Alternator Controller (Voltage Regulator and Over Voltage Sensor) designed for use with 12Vdc aircraft alternators. It combines the OV Sensor and regulator in one unit that is fully pin and function compatible with the Cessna equivalent units. This unit provides Voltage Regulation, Overvoltage Protection, Low/High Voltage indicator pin, self-protecting Field-to-ground short protection, as well as an on-unit Trouble-Shooting Light (TSL). The OV sensor removes power from the regulator thus dropping the alternator off-line when the sysytem voltage exceeds 16 volts. The indicator pins allows a light connected to it and bus to come on whenever the alternator switch is open, the OV sensor is defective (open), or the wire to pin S is open. The unit will turn itself off and turn on a RED TSL light if it senses that the alternator field or field wire is shorted to ground. When the ground fault is removed or repaired, the unit with come back on line (with a GREEN TSL light) once the alternator switch is cycled. If the wire from the alternator battery terminal to pin A is broken, the on-unit light will be OFF. It has two mounting holes and fully pin and function compatible with the Cessna equivalent unit. This is the best unit for Cessna, Beech, and Grummans.
