TYPICAL APPLICATIONS---The voltage monitoring relay is typically applied in dc motor, battery,UPS power supply, dc switchgear, dc panel, industrial control system.

The Composition of This Product Three-phase voltage protector, chronograph and counter are integrated in one relay.. Function This voltage protection relay has overvoltage, undervoltage, phase loss, phase sequence and unbalanced three-phase voltage protection.. Practicality This 3-phase voltage relay does not require an external power supply. Has practical functions power delay, output test, etc. 2 rest modules are optional, manual and automatic.. The LCD can display data for easy reading..

3 INDICATORS-The protector base adopts 35mm rail type or device type, and has two screw hole structures inside, which can be directly installed separately or HT35 rail. Indicated by three indicators normal, phase lossvoltage three-phase unbalance, reverse phase. PHASE LOSS PROTECTION-Phase loss protection means that when the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S. REVERSE PHASE PROTECTION-Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action. VOLTAGE IMBALANCE PROTECTION-Voltage imbalance protection, which refers to a protective measure that will affect the safe operation of the line due to three-phase voltage imbalance. IDEAL FOR-Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, etc.

The base of the protector adopts a rail type with two screw holes, which can be directly installed separately or mounted on the HT35 rail.. Use 5 indicators to indicate normal, phase loss voltage three-phase unbalance, reverse phase, overvoltage and undervoltage.. Phase loss protection means that when the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S.. Overvoltage protection means that the voltage of the protected line is higher than the set value, and the delay is 38S, and the recovery is 620VAC.. Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action..
