LEROY SOMER R230 AVR FOR LEROY SOMER ALTERNATORS
Leroy Somer AEM110RE014, 922-197

Description
Leroy Somer AVR R230,R-series automatic voltage regulators are transistor controlled and monitored, thereby providing excellence regulation regardless of load distortions. The voltage accuracy is +/- 0.5% in a stable state and at constant Speed. With many features fitted as standard, R-series automatic voltage regulators (other than the R230) can be upgraded with modules for parallel operation (current transformer, power factor adjustment and R726 voltage matching) and for three-phase recognition

Encapsulated in resin, R-series regulators have optimum resistance to throb and harsh atmospheric circumstances. The alternator with Shunt excitation is self excited with an R 230 voltage regulator. The regulator monitors the exciter excitation current as a task of the alternator output voltage. Very effortless in design, the alternator with shunt excitation has no sustaining short-circuit capacity. LEROY-SOMER offers an unparalleled range of excitation systems without slip rings or revolving field brushes, the main systems being ACC, with capacitor excitation for low-power, single-phase applications, Shunt, for three-phase and
standard single-phase applications AREP and Shunt+PMG for three-phase applications when discriminating protection or short-circuit capacity are required.

The R230 AVR features the following modification capabilities. (Please note that no adjustments should be made prior to careful consultation of the alternator
installation and maintenance manual)
