Medium Voltage Protection Relay AM4

AM4 series microcomputer protection device are applicable to the user substation which the input voltage is 35kv or above. AM4 can be used to protect and control the user substation, and is be widely used to Power Industry, Water conservancy industry, Traffic Industry, Oil industry, Chemical industry, Coal Industry, Metallurgical Industry and so on.

The advanced and reliable protection principles and algorithms are used in AM4, and AM4 series protection devices have so many advantages such as anti-jamming performance, high reliability, flexible way to achieve protection, communication uses redundancy design.

The device has ample hardware interfaces, such as 12 DI、 5 DO、8AI and so on. The AM4 can be used to communicate with The Acrel-2000 power monitoring system to support Unattended substation system.
