Under Voltage Relay
Applications
-Product is used for highly fluctuating inductive loads such as Air
Conditioning system in industrial and commercial establishments.
It protects the system equipment and load from sudden under
voltage fluctuations.
Function Features
-Controls its own supply voltage (True RMS measurement).
– Measuring frequency range:45Hz-65Hz.
– Voltage measurement accuracy<1%.
– LED indicates relay status.
– 1-MODULE, DIN rail mounting.
