Description
The model SDM530-Modbus is a three phase multi-function energy meter with RS485 Modbus RTU. The unit measures and displays characteristic of three phase four wire supply, including voltage, current, frequency, power, active and reactive energy, imported and exported.
SDM530-Modbus support Max. 100A direct connection, saves the cost and aviod the trouble to connect external CTs, giving the unit a cost-effective and easy operation. Built-in interfaces provide pulse and RS485 Modbus outputs. All the configuration are password protected.
