High Quality DC Meter Can Improve The Fairness Of DC Charging Station

With the development of society and smart grid, the application of DC power is becoming more and more popular, and the measurement of DC power is becoming more and more important. As a DC energy metering device, DC electricity meter has received a lot of attention in the market. In order to meet the demand of intelligent and digital management and different application scenarios, the functions of DC energy meters have been updated and iterated, and the accuracy and reliability of measurement have been gradually improved.






DC meters are mainly used in solar photovoltaic power generation, wind power generation, communication base stations,
EV Charging station metering, DC panels and so on. The following introduction of this rail type DC meter features obvious, outstanding advantages.                         

1It can measure voltage DC 5V~1000V and current up to 2000A.

2, using shunt sampling mode, standard 75mV sampling signal, high measurement accuracy, according to the actual current size of the site can be connected to different current specifications of the shunt

3RS485 communication: used for parameter setting and data reading; support DLT 645 protocol/Modbus protocol, baud rate can be set up to support 115200bps

4Overload alarm function: When the current exceeds the set threshold, the alarm light will be on and alarm will be given

5Support multi-tariff function

6Built-in switching relay output when the overcurrent relay action, can trigger external equipment to steal power

7Firmware upgrade is available through RS485 communication, which can be used to change the function of DC meter in the new demand site.

8, can measure DC power, current, voltage, power, etc., current accuracy 0.5%, voltage accuracy 0.5%, accuracy class 1

9, working power supply using auxiliary power supply 85-300V AC or 85-300V DC, wide voltage range for a variety of scenarios should be used

 

At present, the DC meter has good feedback from customers in the charging pile market and new energy generation market, with practical functions, high communication rate to improve the data transmission frequency, and richer real-time power consumption data. The DC meter can be used for high-power scenario measurement accuracy is particularly important, in the design of the YTL A124 chip, which is a high-precision, low-power analog-to-digital conversion chip, a differential input channel, built-in temperature sensor and high-precision oscillator; designed for DC energy meter measurement of high accuracy to build. The actual accuracy of the din rail electricity DC meter can reach one thousandth, fully meeting the requirements of electric vehicle charging piles for metering and charging.
