Product Description
Product Overview
This product uses a large 160*160 LCD screen with full Chinese display and 12 independent keys. It collects three-phase current, zero-sequence current, and PT voltage. By monitoring the values of these analog signals in real time and comparing them with set values, it can determine line faults and perform corresponding processing. This product has functions such as automatic single-phase grounding fault elimination, interphase short-circuit fault isolation, overload disconnection, undervoltage/overvoltage protection, ensuring the power safety of non-faulty users. It also has local and remote control on/off switch functions. The internal core uses a 32-bit ARM high-speed microcontroller as the main control chip, with advantages such as fast running speed, sensitive and accurate detection, and timely and rapid protection action. The product has local/remote control on/off switch functions, and communication methods such as local serial port parameter setting, GSM SMS control, and GPRS wireless communication are available.
