The F&F CP-721-FPV single-phase programmable DIN-rail relay monitors the mains voltage in photovoltaic installations and activates its output when the voltage exceeds the preset level. The output can switch on an additional load, such as a water heater, while the measured voltage is displayed on the LED screen.
The activation voltage can be set from 245 to 265 V in 1 V increments, while the switch-off hysteresis can be set from 1 to 10 V in 0.5 V increments. The switch-on and switch-off delay can be set from 0 to 999 s in 1 s increments. The relay features thermal protection and returns to normal operation after the temperature drops and 10 minutes have elapsed.
