Cheap price High Current Dc Ammeter - JSY1030 intelligent controller – JIAN SI YAN

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.
