CDV6 Three-Phase Voltage Monitoring Relay (2 Sets Of Outputs)
◼Monitor its own operating voltage (true RMS measurement),
45Hz～65Hz wide frequency measurement.
◼Two sets of output contacts are used for protection and fault
alarm.
◼8 kinds of rated voltages are adjustable, suitable for voltages in
various regions of the world.
◼3-phase 3-wire and 3-phase 4-wire specifications are optional.
◼The voltage measurement accuracy is ≤1%.
◼Anti-harmonic design, optimized for high anti-interference
occasions.
◼The working status of the relay is indicated by an LED indicator.
◼Ultra-small size, only 18mm width, 35mm card rail installation.
Application
◼Used for equipment protection and control (tower cranes, air
conditioners, elevators, agricultural equipment, refrigerated
trucks).
◼Protect the equipment to prevent accidents caused by reverse
operation.
◼Normal/emergency power switch.
◼Prevent phase disconnection of the power load.
