Description

PZ series intelligent DC energy meter is designed for applications such as DC panels, solar power, telecommunications base stations, and charging ports. This series of instruments can measure voltage, current, power, forward and reverse power in the DC system. It can be used for local display and connected with industrial control equipment, computers, from a measurement and control system.

PZ series intelligent DC energy meter also has a variety of external excuse functions for the user to choose from: RS485 communication interface, Modbus-RTU protocol, relay alarm output, digital input/output. According to different requirements, through the instrument panel keys, you can set the ratio, communication parameters

Appearance

The product meets the relevant technical requirements of the standard Q/GDW1825-2013 DC power meter specification，GB/T29318-2012 Non-vehicle charging electric energy metering for electric vehicles, Q/GDW364-2009 Single-phase energy meter specification.

	Voltage and current :1000V, 200A, Default Pulse Constant：100imp/kWh

Function	Measurement of electrical parameters	U, I, P
	Measurement of kWh	Active kWh (positive and negative) Active kWh (positive and negative)
	Multi Tariff	Two sets of timetables, one year can be divided into 4 time zones, each set of timetables can be set to 12 daily time slots,4 rates (F1, F2, F3, F4 are peaks and flat valleys), the minimum interval of the time period is 15 minutes, and the time period can be set across the zero point. (Only for LCD liquid crystal meters)
	Historical data Record	It can count the historical electric energy in the last 12 months (electric energy at various rates). (Only LCD meter has)
	Switch input and output function	PZ72 has two switch outputs and two switch inputs. PZ96 has two switch outputs and four switch inputs. The switch output is relay output, which can realize "remote control" and alarm output. The switch input can not only collect and display local switch status information but also the remote transmission function can be realized through the RS485 of the instrument, that is, the "remote signal" function.
