Voltage and frequency monitor
RP 9800
Article number:
0062263
Type:
RP9800.12 3/N AC400/230V tw=90S
Description
With the voltage and frequency monitor RP 9800, DOLD offers a possibility to disconnect self-generating systems from the low-voltage grid in case of impermissible voltage and frequency values. The voltage and frequency increase or decrease, the reconnection time and the average value of the voltage increase over 10 minutes can be set individually as required using rotary switches.
