Phase unbalance Three Phase Voltage Monitoring Relay undervoltage overvoltage monitor relay

Phase unbalance Three Phase Voltage Monitoring Relay undervoltage overvoltage monitor relay

1 . High-precision

2 . Wide power supply voltage

3 . Installation method

4 . Humanized Voltage Imbalance Protection

phase sequence protector uses a powerful microprocessor chipthe traditional technology uses AC sampling technology, voltage measurement accuracy of ± 1%, the new technology uses true RMS measurement technology, measurement is more accurate, the error is less than 1%, at the same time The three-phase power supply phase voltage values can be displayed separately, which is equivalent to the functions of three voltage meters. ZHRV wide power frequency: phase sequence protector can be applied to 45 ~ 65HZ, to ensure universal use.

The phase sequence protector can be applied to phase voltages of 150-300V (line voltage 250-500V), which greatly reduces the size of the phase sequence protector, making it easy for users to choose, and at the same time reducing the amount of spare parts funds.
Independent Normally Open, Normally Closed Output: The phase sequence protector adopts high-power double-group contact relays, which can independently control devices with different voltage levels, and is more widely used.

The phase sequence protector base adopts rail type and has two M4 screw holes. It can be installed on HT35 rails or M4 screws. The two mounting methods are more flexible and convenient.

The phase sequence protector internally creates an optimized mathematical model that automatically adjusts the operating time based on the three-phase voltage unbalance and does not require user settings.

Sets three-phase voltage display, over-voltage protection, under-voltage protection, phase loss protection (phase-failure protection), voltage imbalance protection, phase sequence protection (wrong phase protection) in one

The three-phase power supply is connected to the three connection points U, V, W (some R, S, T or L1, L2, and L3) of the protector in turn, and the auxiliary contacts of the phase sequence protector generally have a normally open and normally closed state. In the access control loop, it is connected normally or normally closed according to the control principle or wiring diagram. When the phase sequence is wrong or the phase is missing, the auxiliary contact action of the protector is normally open, normally closed, and normally closed. . If it plays a protective role, it should be normally closed contacts.
