Dandong Huatong PDM-803DL-C+E-20A-400V Three-Phase Rail-Mounted Energy Meter

Standard Configuration
1. Comprehensive measurement of over 20 three-phase/single-phase electrical parameters: phase/line voltage, current, active power, reactive power, apparent power, power factor, frequency, etc.
2. Rail-mounted energy meter supports primary current connection (direct access) and secondary connection (via current transformer CT access), suitable for various wiring methods in low-voltage circuits.
3. Four-quadrant energy measurement: active energy (kWh), reactive energy (kvarh).
4. 1 active energy pulse output, 1 LED pulse output.
5. Wide-temperature LCD real-time display; all meter parameters can be set via the display panel or remotely via computer.

Optional Configuration
1. 1 RS-485 communication interface, Modbus RTU communication protocol.
2. 2 digital telemetry inputs.
3. 0.5S class active energy measurement.
4. Multi-tariff (time-of-use) energy measurement.
