Description

The SDM120 Modbus offers a low-cost solution to metering low Amp circuits (45A). The SDM120 range works directly connected to a maximum load 45A AC circuit.

The SDM120 Modbus measures a vast range of parameters, including Voltage, Current and Power Factor.

All SDM120 meters are housed in a 1 Module DIN rail-mounted housing. They also come complete with sealable terminal covers to stop any tampering with the connections.
