1. DC power supply system

The GZDW series DC power supply system is mainly composed of intelligent high-frequency switching power supply modules, central monitoring units, maintenance-free batteries and feeding circuits. It is light weight, small size, high efficiency, pollution-free, highly intelligent, convenient operation and maintenance, and has many advantages such as high reliability. It is an ideal replacement for traditional DC power supply inspection devices.

GZDW series products are mainly used in small and medium-sized power plants, hydropower stations, various substations, switching stations and other users using DC equipment in the power system (such as petrochemicals, mining, railways, communications, building materials, metallurgy, high-rise buildings, etc.), it is an important equipment to ensure the safe operation of power grids and power plants. It provides switching power for various types of circuit breakers (electromagnetically operated, spring-tube energy storage), and provides DC power for various high and low voltage equipment in the secondary circuit, such as instruments, control circuits, relay protection and emergency lighting. Especially when a fault occurs, it is a backup power supply for various control devices and protection devices within the entire substation.

2. Intelligent AC screen

SD series digital AC power panel is suitable for 0.4KV~ 100OKV various voltage levels of substations, power plants, communication rooms and other important AC power consumption places, our company's station AC power panel has been widely used in electric power, transportation, metallurgy, petrochemical, communications, industrial and mining enterprises, municipal engineering and other intelligent AC power applications.

3.communication power supply

Communication power supply is a new generation product launched by our company after the power operating power supply. The design concept of the product follows the trend of the times. The performance indicators of the product have reached the international level and met the 20A-200A power supply capacity requirements. It can be applied to small capacity program-controlled exchanges, mobile base stations, satellite earth stations and other occasions, especially

Suitable for power supply of communication equipment in rural telephone branch offices and microwave relay stations.

The communication power supply module adopts vertical or horizontal installation method. The input and output adopt integrated aviation connectors. It has built-in anti-reverse connection protection. It supports electric heating plugging, making it convenient for this component to form a 48V DC system with a certain capacity configuration. The power supply system can be divided into the following parts: AC distribution unit (including AC input, automatic switching, Class C lightning protection system, AC signal detection), rectification module, battery input and its distribution unit, DC feed-out distribution unit, monitoring module, distribution monitoring module (including AC distribution and DC distribution monitoring).
