PZ72L-D Serie Power Meter
PZ series DC power measuring instrument is designed for DC screen, solar power supply, telecommunication base station and other applications. This series of instruments can measure the voltage, current, power, forward and reverse electric energy in the DC system. It can not only be used for local display, but also can be connected with industrial control equipment and computers to form a measurement and control system, The instrument has a variety of optional functions: RS-485 communication interface, Modbus-RTU protocol; analog output, relay alarm output, switch input/output, etc. According to different requirements, the transformation ratio, alarm, communication, and switch output can be set and distinguished through the buttons on the instrument panel.

| Signal | DC voltage | input range | 0～100V,0～500V,0～1000V,1500V(only PZ96(L)) | |
| Input impedance | ≥6kΩ/V | |||
| DC current | input range | 0～9999A(External shunt or Hall element, programmable range) | ||
| Diverter | The support output are 50mV and 75mV | |||
| Hall sensor | The support output are 0 ~ 20mA, 0 ~ 5V,4～20mA(unipolar) ,etc | |||
| Consumption | ≤1mW | |||
| Overload | 1.2 times continuous normal operation, 2 times continuous 1 second | |||
| Accuracy class | 0.5 class | |||
| Pulse constant | Voltage and current specifications:750V, 300A ,default pulse constant:100imp/kWh | |||
| Voltage and current specifications:1000V,300A ,default pulse constant:100imp/kWh | ||||
| Voltage and current specifications:1000V,200A ,default pulse constant:100imp/kWh | ||||
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 | Count historical energy of last 12 months (energy of each rate)(LCD Meter only) | |||
| Switch input/ output function | PZ72 has two switch output and two switch input. PZ96 has two switch output and four switch input. The switch output is relay output, which can realize remote control and alarm output. The switch input can not only collect and display the local switch status information, but also realize the remote transmission function through the RS485 of the instrument, namely the remote signaling function. | |||
