AVR R726

Automatic Voltage Regulator For Leroy Somer Parts Generator AVR R726

product-R450-1

AVR R450

SX460 self excited brushless type genset voltage regulator is a compatible replacement for Newage Stamford Sx460.

product-R449-1

AVR R449

The circuitry of the R449 Automatic Voltage Regulator (AVR) provides closed loop control of the alternator output voltage by regulating the exciter field current. Which can be powered by either AREP or the PMG field excitation systems and is fitted as standard on 8100 Series Alternators & 9100 Series Alternators.

product-R448-1

AVR R448

The circuitry of the R448 Automatic Voltage Regulator (AVR) provides closed loop control of the alternator output voltage by regulating the exciter field current. The primary winding has a voltage in ratio to that of the alternator (characteristic shunt), the next has a voltage in proportion to the stator current (compound characteristic: booster effect).

product-R438-1

AVR R438

The R438 AVR is powered by two auxiliary windings which are self-sufficient of the voltage match circuit, the first winding has a voltage in proportion to that of the alternator(characteristic shunt), the second has a voltage in proportion to the stator current (compound characteristic: booster effect).

product-R250-1

AVR-R250

Compatible Leroy somer R250 AVR controls the excitation current according to the alternator’s output voltage. With a very simple conception, the shunt excitation alternator is auto excited with a R250 and excitation alternator does not have a short circuit capacity, voltage regulation: around ±0.5%., Phase to neutral voltage sensing.
