Relay FAQ
The relay works irregularly
1) Check whether all wiring is correct, the connection is not firm or the fault caused by incorrect.
2) Check if the leads of input and output are together.
3) For very sensitive SSRs, noise can also couple to the input and cause irregular conduction.
Applications
Used in air conditioning units, elevator machine room, pumps, fans and other motor control applications, as protection of over-voltage, under voltage, phase failure, phase sequence and phase unbalance. When the power supply is abnormal, turn off power supply to protect the equipment
Features
Built-in microprocessors, true RMS voltage measurement, voltage measurement accuracy 5 1%. Measuring frequency 45Hz~65Hz, button setting, LCD display voltage and fault information, protection can be turned on or off. Check phase voltage value by button, with N-phase phase failureprotection. DIN rail mounting
