Electrical Industrial 2280W Direct Current Distribution Cabinet

GZDW series is suitable for substations, power plants, industrial and mining enterprises, electrified railways and high-rise buildings of different voltage levels. It can be used as operating power and control power for high-voltage switches, relay protection and automatic devices. The system adopts the integrated design idea and consists of monitoring module, rectifier module, insulation monitoring module, battery inspection module, switch monitoring module and step-down module. It has advanced technology, reasonable configuration, intelligent measurement and control, and easy operation. It can communicate with the host computer and conveniently realize the four teleoperation functions of “telemetry, remote control, remote signaling and remote adjustment”. It is an ideal DC power supply device for unattended operation.

Advantage:

• High-frequency switching power supply technology, modular design, N+1 hot backup, high reliability.

• The rectifier module adopts hot plugging and online maintenance, which is convenient and quick.

• The charging module adopts the latest international switching technology, which has high conversion efficiency and small electromagnetic drying.

• Hardware low-difference independent current sharing technology, the output current imbalance between modules is typically ±3%.

• Monitor optional LCD screen, touch screen, color touch screen, large screen graphic display, friendly interface, simple and convenient operation.

• Monitoring and real-time monitoring and control of system operation, system setting, information query, and remote monitoring, remote control, remote signaling, and remote adjustment of the system through background monitoring and remote monitoring to achieve unattended operation.

• Monitoring can automatically manage the battery voltage, charge and discharge current and battery temperature compensation accurately. It has over-undervoltage, over-temperature alarm and fault alarm to ensure the battery works in the best condition and prolong the service life of the battery.

• With manual, automatic voltage regulation and branch insulation detection.

• Reliable lightning protection and high degree of insulation protection to ensure system and personal safety.

• Provide RS232, RS485 two communication interfaces, and RTU, CDT, MODBUS three communication protocol options.

• Extended interface for access to other external devices.
