Product Description
1. Product Introduction
The DJKQ-2000C series centralized monitor is the main component of a complete set of high-frequency switching DC power supplies for electric power. It can form an intelligent monitoring system for the DC system with the monitoring and dispatching center computer in the background through telephone network, optical fiber, standard serial interface or network. The centralized monitor monitors the charger, storage battery, DC bus, insulation monitoring device, AC/DC power distribution device, etc. of the DC system in a decentralized control manner, and completes communication with the upper computer to achieve four remote functions of the DC system, including "remote signaling", "telemetry", "remote control", and "remote adjustment". It is widely used in large and medium-sized power plants, 500 kV and above substations, and other places, It is also applicable to 220kV and below substations, user stations, small power plants, and other places.
