R220 AVR For Leroy Somer
R220 Generator AVR
The alternator with Shunt excitation is selfexcited with an R220 voltage regulator. The regulator monitors the exciter excitation current as a function of the alternator output voltage. Very simple in design, the alternator with shunt excitation has no sustaining short-circuit capacity
Technical Features:
Storage : -55°C ; +85°C
Operation : -40°C ; +65°C
Voltage regulation: ± 0.5%.
Voltage supply/sensing range 85 to 139 V (50/60 Hz)
Rapid response time (500 ms) for a transient voltage variation amplitude of ± 20%
Voltage setting P1
Stability setting P2.
Power supply protected by 8 A fuse, slowblow action (tolerates 10 A for 10 s)
The fuse is impregnated in the resin, therefore it can not be replaced.
Frequency: 50 Hz with ST3 jumper - 60 Hz without ST3 jumper.The size of the screwdriver tip used to adjust the potentiometer is 2.5 mm
