Application
-Product is used for highly fluctuating inductive load such as Air Conditioning system inIndustrial and commercial establishments. It protects the system equipment and load from sudden under voltage fuctuations.
Feature
- Controls its own supply voltage(True RMS measurement).
- Measuring frequency range:45Hz-65Hz
- Voltage measurement accuracy<1%.
- Relay status is indicated by LED.
- 1-MODULE,DIN rail mounting.
