CP-721-FPV
Voltage relay
for photovoltaic systems
The CP-721-FPV 1-phase voltage relay is dedicated for photovol-
taic systems. In the event of detecting an excess of the preset
voltage level, the output relay will switch on, with the help of
which it is possible to switch on an additional consumer (e.g.
a boiler), thus increasing the self-consumption of energy in the
domestic installation and reducing the risk of the photovoltaic
inverter switching off due to excessively high mains voltage.
» Output circuit switched on when voltage is exceeded, swit-
ched off when voltage decreases;
» Precise adjustment of switching voltage;
» Programmable delay for relay activation and deactivation;
» Programmable voltage hysteresis for relay deactivation;
» Direct control of loads up to 16 A;
» LED display for continuous voltage monitoring.
