Leroy Somer AVR R731 automatic voltage regulator for generator sets

See details:

Input voltage:

High voltage tap (400V):340V-5% to 480V=5%

Low voltage tap (110V):90V-5% to 140V+5%

Medium voltage outlet (230V): 200V-5% to 240V+5%

Maximum current for 10s:10A

Internal voltage rheostat:

The voltage can be adjusted using the internal rheostat P1. This rheostat is designed to provide +/-5% adjustment from any voltage within the above voltage ranges.

Remote voltage rheostat:

If necessary, remove the ST10 jumper to connect a remote voltage rheostat.

A 470 Ohms - 3W rheostat can be used for a +/-5% voltage adjustment range or a 1k Ohms - 3W rheostat for a +/-10% voltage range.

An ST1 jumper was included on older R731 modules to increase voltage adjustment range, but was no longer manufactured.

voltage drop

Current sensing: CT for // operation

Location: standard line 1 (U), optional line 2 (V).

- Maximum continuous current: 1.3A

- Rated current: 1A

- Maximum current in 10s: 10A

Voltage drop rheostat:

The P2 rheostat on R731 can be used to adjust the voltage drop. It is designed to provide a minimum voltage drop of 8% at 0 power factor and 1A from the parallel CT.
