Product Details

PZ Series Intelligent DC energy meter

 

    PZ Series Intelligent DC energy meter is designed for DC panel, solar power supply, telecom base station, charging pile and other applications. This series of instruments can measure the voltage, current, power, forward and reverse energy in DC system. It can not only be used for local display, but also be connected with industrial control equipment and computer to form a measurement and control system. At the same time, it has a variety of peripheral interface functions for users to choose: with RS-485 communication interface, using Modbus-RTU protocol; It can be equipped with relay alarm output and switch input / output. According to different requirements, through the instrument panel buttons, the transformation ratio and communication are set and controlled.

Functions

Measurementmeasure DC voltage U, current I and power P,When the current input is hall sensor(4~20mA output),the current only support unipolar metering.
 Meteringmeasure 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 functionEach 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 functionCount historical energy of last 12 months (energy of each rate)(LCD Meter only)
 Switch input/ output functionPZ72 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.
 DisplayLCD(backlight delay time adjustable)or LED
