OVERVIEW

PZ Series DC energy meter is designed for DC panel, solar power supply, telecom base station, charging pile and other applications. This series of energy meter 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.

MAIN PARAMETERS

Technical parameter		index
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.
