Jiangsu factory direct chi Shengda DC panel 1.6 meters small computer system

A: DC small screen Introduction Name: DC-screen computer system 1.6 m 1.6 m small DC panel for small systems is Zhaopin Shengda Technology designed for small-capacity systems designed; suitable for small switching stations, small user substation, the system uses the integrated design by rectifier module, control module, buck units, power distribution unit and battery box composition; with small, simple structure, independent component system features; monitoring module uses LCD Chinese menu of automated system monitoring and battery management functions complete with connecting four remote interfaces and automation system that provides two RS232 and RS485 communication interface options, to provide RTU, CDT, MODBUS Statute three communication options. Two: DC-screen works simply, DC panel is to provide a stable DC power supply equipment. DC-screen two-way exchange of electricity through one AC input switching means, to each charging modules. DC screen charging module will enter the three-phase / single-phase AC power is converted to DC power to charge the battery, at the same time to switch on the load, in addition to closing bus through the pressure-relief device power control bus. When the mains power failure or abnormal discharge from the battery emergency power supply; DC panel system of each monitoring unit basis by management and control of the main monitor, via the communication line to each base monitoring unit collected information to the main monitor unified management. DC system main monitor display a variety of information, users can query information and touch screen operation, the system can also access information to a remote monitoring system. DC dismiss the basis of the exchange monitoring, DC monitoring, switch monitoring, you can also configure the insulation monitoring, battery inspection function to the DC system to conduct a comprehensive monitoring. Three: DC panel features ● suitable for small systems constitute 38AH / 220V, 65AH / 110V or less systems. ● module, control unit and step-down units using hot plug structure, installation and maintenance. ● can be installed three 2.0A / 220V, 4.0A / 110V natural cooling module. ● buck buck silicon chain unit with automatic function, the maximum current of 2A, the impact of current 30A / 0.5S. ● Monitor uses LCD display, Chinese menu, button operation, enabling the system parameters, the system displays the operating parameters, system fault indication and system calibration. ● Monitor has automatic battery management functions. ● Provide RS232 and two RS485 communication interface options, to provide RTU, CDT, MODBUS Statute three communication options can be connected with power plant automation systems. ● Monitor realization battery voltage, voltage controlled parent, mother of current control, battery charge and discharge current, module status detection. ● power distribution unit provides two AC input (optional power supply all the way PT), 3-way feed output. ● PT power supply system automatically limits the output power.
