1000V DC Solar Voltage Current Power Meter Bidirectional RS485

Solar Voltmeter Current Analyzer Solar Bidirection Dc Smart Voltage Power Meter RS485

PZ series intelligent DC energy meter is designed for applications such as DC panels, solar power, telecommunications base stations, and charging posts. This series of instruments can measure voltage, current, power, forward and reverse power in DC system. It can be used for local display, and connected with industrial control equipment, computers, form a measurement and control system. And it has a variety of external excuse functions for the user to choose: 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.
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.

FREQUENTLY ASKED QUESTIONS

1.Do you use a transformer to measure the current in your instrument?

Answer yes to add, instrument input current 1-5A voltage 0-380V over the rated value is the need for another transformer.

2.What size of transformer is appropriate?

Meter current measurement range is AC-0-5A(market instrument standard). For example, if you need to measure current range is AC0-100A, you only need to buy 100/5A current transformer. The principle is: your current input terminal

Aco-100a is reduced by 100/5=20 times through the current transformer, and then the current passing through the instrument is ACO5A. The current ratio in the instrument can be set to 20, that is, the amplification is 20 times. In this way, the actual input current can be restored to show 100A--100/5--5A--5*20--100A

3.Do we still need to power up the meter?

Answer of need, be same with our household electric appliance, after electricize ability can work, household electric of 220V is ok, if you do not have such only working range is in 85-270V between ok.

4.How about the reliability of the instrument?

Answer: our instruments are - secondary yield of 99%, all products before leaving the factory after 72 hours of aging, computer automatic measurement precision.

5.What do you mean by calling the police?

Answer: alarm is the relay control output, output switching signals such as: current upper limit alarm, set the current over a certain value of automatic trip can effectively protect the equipment from damage
