Phase Unbalance Three Phase Voltage Monitoring Relay 2 C/O Contacts CE Cetification

Phase Unbalance Three Phase Voltage Monitoring Relay 2 C/O Contacts CE Cetification

High-precision: phase sequence protector uses a powerful microprocessor chip, the 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.
Wide power supply voltage: 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.

Installation method: 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.
Humanized Voltage Imbalance Protection: 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, using a powerful microprocessor chip and non-easy Loss of storage technology, display using high-definition ultra-wide temperature Chinese liquid crystal, with full-featured, stable performance, intuitive display, easy operation.
