Product Desciption

Leroy Somer AVR R220, Generator Voltage Regulator R220

The R220 is an IP00 product. It must be installed inside a unit so that this unit's cover can provide IP20 minimum total protection (it must only be installed on LS alternators in the appropriate location so that when viewed externally, it has a higher degree of protection than IP20).
SHUNT SYSTEM:

SHUNT excitation system:
The alternator with Shunt excitation is self-excited with an R 220 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.
R220 A. V. R. Characteristics

Specification

- 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, slow-blow 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
R220 AVR option:
- Potentiometer for remote voltage adjustment, 1000 Ω / 0.5 W min: Adjustment range ± 5%
- Remove the ST4 jumper
For wiring up the external potentiometer; The "earth" wires must be isolated as well as the potentiometer terminals(wires at the same voltage as the power).
