System characteristics of DC screen: 1. High reliability of DC screen: 1.Adopt modular design of switching power supply, N+1 hot backup.2.The charging module can be hot-swapped and unplugged, and the average maintenance time is greatly reduced.3.The power bus and the control bus can be directly powered by the charging module alone, and can be backed up by the voltage reduction device.4.Hardware low-difference independent current sharing technology, the maximum unbalance of output current between modules is better than 5%.5.Reliable lightning protection and electrical insulation measures, the insulation monitoring device can monitor the insulation of the system in real time to ensure system and personal safety.6.The system design adopts IEC, UL and other international standards, and the reliability and safety are fully guaranteed.2. High-intelligence of the DC screen: the monitoring module adopts large-screen LCD Chinese character display, sound and light alarm.The parameter setting of each part of the system can be carried out through the monitoring module.The module has the function of smoothly adjusting the output voltage and current, and has the function of battery charging temperature compensation.With multiple expansion communication ports, you can access a variety of external smart devices (such as battery testers, insulation monitor devices, etc.).The combination of modern power electronics and computer network technology provides support for “remote measurement, remote control, remote signaling, and remote adjustment” of the power supply system to realize unattended operation.Battery automatic management and protection, real-time automatic detection of battery terminal voltage, charging and discharging current, and intelligent energy control of battery floating charge, with battery over-voltage and over-current sound and light alarms.The system adopts monitoring device built-in insulation monitoring, battery detection, grounding line selection, battery activation, silicon chain voltage regulation, central signal and other functional units, which are greatly convenient for users to use; the system adopts unique “one-line” wiring technology, which is greatly convenient for large-capacity In-screen wiring of the DC system, convenient for user maintenance.1. The charging module adopts natural cooling, which greatly improves the mean time between failures, and can be used in places with relatively harsh environments; 2. The charging module can be plugged and unplugged under power, and the average maintenance time is greatly reduced; 3. Adopt the latest international soft switching technology, and the main components adopt high-quality brand-name products; 4. Hardware low-difference independent current sharing technology, the maximum unbalance of output current between modules is better than ± 5%; 5. Reliable lightning protection and high-level electrical insulation protection measures, insulation monitoring device real-time monitoring of system insulation, to ensure system and personal safety; 6. The monitoring module adopts large-screen LCD touch screen display, real voice alarm; 7. The monitoring program adopts object-oriented design ideas and modular programming, which is conducive to program maintenance and upgrade; 8. The parameter setting of each part of the system can be carried out through the monitoring module, with detailed online help function; 9. It has advanced functions such as smooth adjustment of output voltage and current, automatic battery temperature compensation, etc.; 10.Combining modern power electronics technology with computer technology to realize “remote measurement, remote control, remote signaling, and remote adjustment” of the power supply system and realize unattended operation; 11. Battery automatic management and protection, real-time automatic monitoring of battery terminal voltage, charging and discharging current, and control of battery equalization and floating charging, with battery over-voltage and over-current acousto-optic alarms.12.The device can be supported by programs through public telephone lines to realize remote maintenance and diagnosis-DC screen monitoring module.
