  • Describe
  • PZ-Series Intelligent DC Energy Meter – the compact, panel-mounted solution that turns any DC source into a revenue-grade data node. Engineered for solar arrays, battery racks, EV charging piles, telecom shelters and DC switchboards, it simultaneously tracks voltage, load current, instantaneous power and bi-directional energy with 0.5 % accuracy. A high-contrast LCD gives on-site operators an at-a-glance view of kWh, kW, Ah and state-of-charge, while the built-in RS-485 port speaks Modbus-RTU for seamless SCADA, PLC or cloud-gateway integration. Two configurable digital inputs (2DI) monitor breaker status or door contacts; two solid-state outputs (2DO) drive local alarms, contactors or remote-reset relays without extra modules. Need to power transducers or a LoRa radio? The meter’s on-board 12 V / 200 mA auxiliary output eliminates an external supply. Time-of-use billing is built in: program up to four tariff periods and eight seasons through the front-panel buttons to automatically accumulate peak, off-peak and shoulder energy registers. DIN-rail or base-plate mounting, 18–300 V DC or 90–265 V AC universal supply, 4 kV isolation and –25 °C…+70 °C operation make PZ the smartest way to measure, bill and control every watt that moves through modern DC systems.

    Functions

    Measurement

    measure DC voltage U, current I and power P,When the current input is hall sensor(4~20mA output),the current only support unipolar metering.

     

    Metering

    measure current combined energy, forward energy and reverse energy,When the current input is hall sensor(4~20mA output),the electric energy only support unipolar metering.

     

    Time sharing function

    Each year can be divided into 4 time zones. Each time zone table can be set with 12 daily time periods and 4 rates (F1, F2, F3, F4 are SHARP,PEAK,SHOULDER and OFF-PEAK). The minimum interval of time periods is 15 minutes. Time periods can be set across zero(LCD Meter only)

     

    Historical data statistics function
