See Details:
Input voltage :
High voltage tap (400V):340V-5% to 480V=5%
Low voltage tap (110V):90V-5% to 140V+5%
Medium voltage tap (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 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.
voltage droop
Current sensing : C.T. for // operation
Location : standard line 1 (U), option line 2 (V).
- Maximum continuous current : 1.3A
- Nominal current : 1A
- Maximum current for 10s : 10A
Voltage droop rheostat :
The P2 rheostat on the R731 can be used to adjust the voltage droop. It is designed to provide a minimum voltage droop of 8% at 0 power factor and 1A from the paralleling CT.
