SDM320Y is Single Phase Energy Meter with Built-in Relay for Prepay System.

The meter is with excleent reliability that can display remaining capacity, available remaining, total power consumption/ purchase of electricity, credit line, overdraft consumption, load threshlod, pay model, voltage, current, active power, active energy, import energy, export energy, power factor, frequency and time ect. The reactive power, apparent power can be read by Modbus.

It is suitable for real-time power monitoring system and has the characteristics of multifunction, multi-purpose, high stability and long life.
