EKV8 3-Phase Voltage Relay

EKV8 3-Phase Voltage Relay
Technical Data

■ Applications

- Control for connection of moving equipment(site equipment, agricultural equipent, refrigerated trucks).
- Control for protection of persons and equipment against the consequences of reverse running.
- Normal/emergency power supply switching.
- Protection against the risk of a driving load(phase failure).

■ Applications

- Controls its own supply voltage(True RMS measurement).
- Set 8-level rated operating voltage through knob.
- Measuring frequency range: 45Hz-65Hz.
- Voltage measurement accuracy<1%.
- Relay status is indicated by LED.
- 1-MODULE,DIN rail mounting.
