ZEFTRONICS VOLTAGE REGULATOR
R15100 REV. A

The R15100 Rev A is a 14Vdc solid state Alternator Controller (Voltage Regulator) designed for use with 12Vdc aircraft alternators. This unit provides Voltage Regulation, Field induction protection, Low/High Voltage indicator pin, and self-protecting Field-to-ground short protection, as well as an on-unit Field Fault/Function indicator. 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 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 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. The R15100 Rev A has two mounting holes and fully pin and function compatible with the Cessna equivalent unit.

Benefits:

• Increased Regulator life. Reduced panel lights flicker.
• Warns the Pilot of Low & OV Conditions.
• Protects against grounded alternator field.
• Identifies grounded field. Reduce trouble-shooting time.
