Replace Leroy Somer Voltage Regulator Genset AVR R180

Product Description

Product Description
The R180 is a fully solid-state automatic voltage regulator (AVR) which is used for excitation of a brushless alternator powered by a Permanent-Magnet (PMG) exciter or by auxiliary windings. The R180 has an accessory input, which can be used as a remote potentionmeter terminal when connected to a 1 KΩ potentionmeter or takes ± 4.5V DC in order to change the terminal voltage.
The AVR output is limited to 6A. This limiter is delayed type so that it does not interfere with field forcing. in the event of loss of thr sensing input. thr AVR provides 9A DC excitation current for 5 seconds and reduces the excitation current. The R180 is triggered from the alternator remanent voltage.
