I、Intelligent DC panel power supply device
The company designs and produces an intelligent DC panel to meet the need of the electrical power system. This product has many types and specifications to meet the need of DC panel power supply in the large, medium sized and small power stations, substations and other industries. Its main properties are high stability in operation and interference resistance, small ripple factor, and high technical accuracy. In addition, it also has a perfect protection function. It is easy to adjust the set values directly. The two routes of AC input can be switched in between freely through the computer control with high reliability. The product charges the storage battery strictly according to its charging curve to avoid over or under recharging and extend the operation life of the battery. For the type with the microprocessor control, there is also a data logging function for the battery to track and test each working point for multi protection. It can realize collective monitoring and unattended duty through the communication with the upstream computer via the standard communication interface.
The application scope of the DC panel power supply
  • Metallurgy and mine; railway and petrifaction
  • Medical treatment and sanitation; post and communications
  • Finance and computer network
  • Power plant, substation, and monitoring
