General Description / Specifications

The R 731 optional three phase sensing module is designed to be used with the R438, R448, R449 single phase sensing voltage regulators.

CHARACTERISTICS:

The voltage sensing is done with three 2VA single phase transformers.
Input voltage :
- High voltage tap (400V): 340V-5% to 480V=5%
- Medium voltage tap (230V) : 200V-5% to 240V+5%
- Low voltage tap (110V) : 90V-5% to 140V+5%

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 required, remove the ST10 jumper in order 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 the voltage adjustment range but was discontinued.
