Product 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.
