0.001CBM Volume Automatic Voltage Regulator Leroy Somer AVR R250
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%.
Voltage regulation: around +/- 0.5%
Voltage supply/sensing range 85 to 139 V (50/60 Hz)
Rapid response time (500ms) for a transient voltage variation amplitude of +/- 20%
Voltage settin P1
Stability setting P2
Power supply protected by 8 A fuse, slow-blow action (tolerates 10 A for 10 S)
