DP-M1 Cheap Factory Price 0-1000V Charging Pile Multi Channel DC Power Meter
Description
This product is an intelligent isolation transmitter for comprehensive measurement of single-phase electricity, which can measure all parameters of DC single-phase loop. For the product uses the 24-bit dedicated AD chip, the dynamic range ratio is as high as 1000: 1. And the measurement parameters include various electrical parameters such as voltage, current, power, and accumulated power.
Furthermore, DP-M1 is with high precision, good stability and high communication rate, and also owns full isolation processing technology, strong anti-interference ability. The measured power parameters are transmitted remotely through the RS-485 digital interface output. In addition, the MODBUS protocol of the product is fully compatible with the MODBUS (RTU) protocol in various configuration software or PLC equipment.
Features
l Optional power supply: DC: 10-30V or 10-55V.
l The sampling period has seven rates of 20ms, 40ms, 60ms, 80ms, 100ms, 400ms, and 1000ms that can be set.
l With odd parity, even parity, no parity, 2 stop bits and other communication formats can be freely set.
l Electricity has the function of accumulating and storing forward and reverse respectively, and has the function of saving after power failure.
l With a variety of working and running indicators, the red light indicates the normal operation of the product (flashing at 100mS), and the green light indicates the product communication.
l With one relay alarm output.
l Strong anti-interference ability, the input, output and power ports can resist surge voltage up to 2KV or more.
l AC and DC universal measurement; with absolute value and signed value of two measurement methods.
l High-precision and high-resolution type can be customized, with a resolution of 1/50,000.
