Power protection is a multi-functional three-phase power system or three-phase power equipment monitoring and protection equipment. Set three-phase voltage display, over-voltage protection, under voltage protection, phase protection (phase protection), phase sequence protection (phase protection) in one. Using Chinese liquid crystal display, with full-featured, stable performance, easy operation and so on. Power supply protection DFY-5 real-time display three-phase power supply voltage, and in the power overvoltage, undervoltage, phase loss, Power Surge Protector fault phase failure through the form of relay output to the user to provide alarm output and protection circuit action output contacts Control signal, play the role of alarm and protection. Is to replace the traditional phase sequence relays and voltage relays of high-tech products.
Power protection is in the power supply overvoltage, undervoltage, phase loss, fault phase fault through the form of relay output to the user to provide alarm output and protection circuit action output contact control signal, play an alarm and protection. Is to replace the traditional phase sequence relays and voltage relays of high-tech products. Power Surge Protector Power protection can be widely used in a variety of low-voltage electrical control system to replace the traditional phase sequence relay and over-voltage protection, especially for elevators, cranes, machine tools, compressors and other frequent start-up equipment.
Power protection using a powerful microprocessor and non-volatile storage technology, Power Surge Protector display the use of high-definition ultra-wide temperature Chinese LCD, with full-featured, stable performance, intuitive display, easy operation, and has the characteristics of sound and light alarm.
Power protection using panel-mounted, elegant, Power Surge Protector beautiful appearance, for low-voltage electronic control device to enhance the grade.
Power protector function
1, display voltage: display the operating voltage value
2, over / undervoltage protection: the voltage is too high or too low, cut off the power supply equipment.
3, phase protection: When the three-phase power phase or serious imbalance when the equipment power off.
4, phase sequence protection: Power Surge Protector When the three-phase power phase sequence error when the device power off.
5, sound and light alarm: the occurrence of the above occurs when the sound and light tips.
6, rated control voltage Us: phase voltage AC-220V line voltage AC-380V.
7, the supply voltage error: -15% - +10%.
