100AH 120AH GZDW Power Distribution Cabinet 200AH Power Supply Low Voltage Switchgear

Main Performance of DC Distribution Panel

1. The main performance features are stable operation, strong anti - interference ability, low ripple coefficient, and high - tech level.
2. It is divided into two structural categories: single - body cabinet and split - body cabinet.
3. The products are widely applied in power plants from 500KV to 10KV of different voltage levels, hydropower stations and various substations, switching stations and user substations, providing DC power sources for circuit - breaker closing and secondary loop instruments, relay protection and accident lighting.
4. The system adopts an integrated design concept, composed of a monitoring module, rectifier module, insulation monitoring module, battery inspection module, switching - value monitoring module, voltage - dropping module, etc. It has the characteristics of advanced technology, reasonable configuration, high intelligence, and simple operation.
5. It can be interconnected with the upper - level machine, realizing "remote measurement, remote control, remote signaling, remote adjustment" functions, which is especially suitable for unattended requirements.

Characteristics of DC Distribution Panel System

1. Adopt the modular design of high - frequency switching power supplies with N + 1 hot standby.
2. Have an ultra - wide voltage input range, strong adaptability to the power grid, and can be used in relatively harsh environments.
3. The charging module is plug - and - play, and can be maintained online for quick replacement.
4. Have reliable lightning and electrical isolation protection measures to ensure system and personal safety.
5. Adopt a large - screen touch screen, a dot - matrix liquid crystal display, and CCFL backlighting, with intuitive and convenient real - time display and operation.
6. Through the fault self - diagnosis program, the system can conduct comprehensive inspections, be easy to operate, and truly achieve human - machine interaction.
7. The monitoring module can automatically complete the accurate management of battery voltage, charge - discharge current and temperature compensation, ensure the battery operation in the best state, and extend the battery service life.
8. Adopt an intelligent controller - centered distributed monitoring system, modular design, and implement comprehensive "four - remote" and unattended monitoring and control of the power supply system.
9. The battery management unit can automatically monitor the battery pack voltage, charge and discharge current, and control the charging and discharging of the battery pack. In case of over - voltage / under - voltage and over - current alarm and other functions.
10. The software and hardware of the monitoring system adopt an open - design, which can be added or modified at any time according to different user needs to adjust the monitored and controlled parameters.
11. A set of monitoring system supports dual - string battery packs, three - group charging devices, and bus - section mode monitoring. It can realize independent management of the two - string battery packs with a charging completion rate of over 95%. The internal and external names are clear, ensuring the safety of the battery packs.
12. The main electrical components are all above the domestic well - known brands, with reliable power distribution protection.
13. Provide two communication interfaces of RS232 and RS485, and three communication protocols of RTU, CDT, and MODBUS.
