BD series power transmitter is a device that converts electrical parameters such as current, voltage, frequency, power, and power factor in the grid into linear DC analog signals or digital signals through isolation. BD-3I3 measures three-phase AC current, and outputs 4-20mA or 0-5V DC signal through isolation and transmission, and RS485-MODBUS communication is optional.
