GZDW series of DC power supply system is mainly composed of high-frequency switching module, central control unit, AC and DC power distribution unit, lead-acid (alkaline) battery and output feeders etc, at the same time, elements of each part of the system are high reliable device: switching module of EMERSON, MCB&MCCB of SIEMENS, etc.

With the rapid development of electric power technology and abroad and large-scale technical transformation and innovation, DC switching module and DC systems have become increasingly demanding. The last technology of silicon controlled rectifier （SCR）and magnetic saturation type constant low precision of voltage and current, large ripple factor, harmonic pollution effect the input power grid, it has been unable to meet the needs the development of electric power engineering and industry in our country. Our production of GZDW series of intelligent high frequency switching module constant voltage and current of high precision, fast response speed, low noise, high efficiency, the system is equipped with communication interface (RS485/RS232), It can realize communication function and automation system through the MODBUS and other communication protocol. Module redundancy backup according to N+1 type, it make the power system operation more safe and reliable. Our products are widely used in large and medium substation projects, power plants, hydropower stations, building construction, factories, etc. They provide the power for the control system, protection, remote communication and DC lighting system.

●Intelligent high-frequency switching module is EMERSON or other famous brand. Quantity of module is N+1 hot standby, and current is 10A 、20A 、30A 、40A.

●Controller adopts EMERSON PSM system or SIEMENS S7-200 PLC, they are stable, high speed of parameter processing, high precision data acquisition.

●HMI adopts EMERSON Siemens 6~10 inch color-touch screen, which display multi-interface for the system parameters, status, information and operating friendly.

●Automatic switchover power, The system is automatically restored after power is coming.

●The system is equipped with LA and SPD, which can effectively prevent surge and high harmonic impact.

●It has RS485、RS232、modem,、Ethernet port etc, which support modbus and other protocol.It’s convenient to communicate with remote monitoring system.

●Battery inspection unit is domestic famous brand, it can realize intelligent management of the battery.

●Professionally make electric power supply system with various specs and other requirements.
