Product Description

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.

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.

Features:

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
