SDM120DB Single Phase kWh Meter | Meters & Timers
The SDM120 family of meters have been produced to offer a low-cost solution to metering low Amp circuits. The SDM120 range work directly connected to a maximum load 45A AC circuit. All versions of the SDM120 meter come with a pulsed output for remote monitoring. All SDM120 meters are housed in a 1U Din Rail mounted housing. They also come complete with sealable terminal covers to stop any tampering with the connections.
Measured Parameters
