Single-Phase AC Power Collector

Single-Phase AC Voltage Current Power Collector

Introduction:
This product is a collector for comprehensive measurement of single-phase AC power, equipped with one relay for automatic alarm output, with a dynamic range ratio of up to 1000:1. It can measure various electrical parameters such as voltage, current, frequency, active power, reactive power, power factor, harmonic power, and cumulative power based on true effective value. High precision, good stability, and high communication speed. Fully isolated technology with strong anti-interference ability. RS485 output enables remote transmission, and the product's Modbus protocol is fully compatible with various configuration software or Modbus (RTU) protocol in PLC devices.

1.The sampling period can be set at seven rates: 20ms, 40ms, 60ms, 80ms, 100ms, 400ms, and 1000ms.
2. It has multiple communication formats such as odd parity, even parity, no parity, and 2-stop bits that can be freely set.
3. The electricity has the function of accumulating and storing in both forward and reverse directions, and has the function of saving in case of power failure.
4. Multiple work operation indicator lights, with a red light indicating normal product operation (flashing for 100ms) and a green light indicating product communication.
5. Equipped with a relay alarm output, it can set four threshold alarm functions: upper limit, lower limit, within area, and outside area.
6. Strong anti-interference ability, input, output, and power ports can withstand surge voltages of up to 2KV or more
7. True RMS measurement, applicable to the measurement of variable frequency equipment.
8.Available with wide power supply options: DC: 10-30V or 10-55V.
