Description

The consumption of electric energy is largely concentrated in low-voltage distribution terminals. In order to strengthen the measurement, assessment and management of terminal electric energy, and facilitate users’ on-site use, transformation and upgrading. Jsy1030 intelligent controller aims at the inconvenience of using and installing the traditional wall mounted watt hour meter on site, and designs a miniature guide rail mounted watt hour meter, which has the advantages of high measurement accuracy, strong overload capacity, stable and reliable performance, wide working voltage range and low power consumption. And its small size, light weight, modular structure, can be used with miniature circuit breakers installed in the distribution box to achieve terminal distribution energy measurement.

Features

1. Collect single-phase electrical parameters, including voltage, current, active power, active electric energy, power factor, frequency, etc., with complete information.

2. It adopts special measurement chip and AC true RMS measurement method, with high measurement accuracy.

The communication protocol adopts standard Modbus RTU mode, which has good compatibility and is convenient for programming.

3. The over-voltage, under voltage and over-current thresholds can be set. When the controller detects that the voltage or current exceeds the threshold for 5 seconds, it will automatically disconnect the load.

4. RS-485 communication interface with ESD protection circuit.

5. Industrial chips are used, with perfect lightning protection and anti-interference measures to ensure reliability.

6. Beautiful and compact appearance, light weight, excellent and reliable performance.

7. 35mm DIN rail or plate front installation is adopted.
