R220 AVR is used in LSA40 & LSA42.3 series alternators. The R220 AVR is a simple design, inexpensive and a perfect solution for small generators especially for standby or prime continuous applications.
Standard : for LSA 40 alternators.
Adapted to the SHUNT and AREP excitation system
Main characteristics
Voltage regulation +/- 0.5% at steady state and constant speed.
Response time 500 ms
Nominal excitation current : 3A
Maximum excitation current 7A for 10 sec.
Maximum excitation current 7A for 10 sec.
Maximum excitation current 7A for 10 sec.
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.
