The DDS238-2 SW single phase watt-hour meter is designed to measure single phase two-wire AC active energy and variable parameter. All of its functions meet the technical requirement for class 1 single phase watt hour meter by the standard of IEC61036. The durable meter is high in stability and overload capability, low in power loss and small in volume.
Basic Function
1. The single phase watt-hour meter can measure bi-directional total active energy, as well as the reverse active energy in the total active energy.
2. Its LCD display is available with backlighting.
3. The meter displays realtime voltage, current, power, frequency and power factor.
4. Pulse LED indicator is available to indicate the operation status of meter, and pulse output comes with optical coupling isolation.
5. The product adopts 35mm DIN-rail installation
Optional Function
1. The meter can measure and display the total forward/reverse active energy.
2. Energy-reset function: Under energy-reset mode, the display of total energy display won't be affected.
