Overview
AM series protection relay are applicable to the user substation which the input voltage is 35kv and below. We adopt mature technology solutions to ensure the quality of the AM relay.The AM relay are widely used in substations, subsection posts and ring main units for office buildings, commercial buildings, communication buildings, mine buildings and so on.4 current input, 3 voltage input, 8DI, 5DO; Auxiliary power supply adapts with AC220V, DC220V, DC110V, AC110V;DC48V,DC24V; 1 RS485 serial communication, IEC60870-5-103 and Modbus-RTU; more than 200 sequence of event records, more than 400 system logs, and more than 10 seconds tripping context records; Powerful graphic programmable Logic.LCD Display
