The IM300 series of power intelligent monitoring instruments are intelligent devices for medium and low voltage systems (6 to 35kV and 0.4kV). They have powerful data acquisition, processing, statistics and control functions, enabling measurement and calculation of basic single-loop AC parameters. Power accumulation, fault record, 2 to 31 harmonic monitoring functions, 4-way switch input monitoring, 2-way relay output, 1 channel 4~20mA DC transmission output, over-limit alarm and other functions. The IM300 provides a communication interface that supports the RS485 interface MODBUS communication protocol and is connected to a computer monitoring system.
