QN-DC/ 30KW-200KW DC Distribution Cabinet
Product Description
The QN-DC DC Power Distribution Cabinet is a newly introduced product by China Power. It is primarily designed for LED display system applications with input AC 380 V and output DC 200–250 V.
Functions and Performance
1. Eliminates harmonics generated by switching power supplies in LED display systems
2. Significantly reduces leakage current in LED displays
3. Noticeably improves low-gray-level display performance
The cabinet converts AC 380 V input power into a DC 200–250 V output using a modular design. The DC output power adopts a multi-step soft-start mechanism, with each startup step rated at 3.5 kW, effectively reducing inrush current and improving system stability.
It enables control methods covering Manual Control, Scheduled Control, Remote Control via RS-485 and Ethernet Control.
It supports protection functions cover Overcurrent Protection, Short-Circuit Protection, and Overtemperature Protection.
In addition to the DC 200–250 V output, the DC power distribution cabinet also provides a DC 48 V output, which can be used in combination with the DC 220 V output to meet different system requirements. The two DC output configurations are similar in cost and are significantly higher in cost compared with traditional AC 220 V output solutions.
Functional Features
1. Control Modes: It supports Manual Control, Remote RS-485 Control, Scheduled Control, and Network Control.
1)Remote RS-485 Control: Third-party platform integration, Protocol: Modbus RTU
2) Network Control: Manufacturer proprietary protocol, Protocol: Modbus TCP
3) Scheduled Control: Up to four time periods can be configured per day, with weekday-based start/stop settings and support for cross-day scheduling.
4) Manual Control + Automatic control: One-key start/stop via front panel button and dedicated one-to-one power switching
2. Operating Characteristics: features strong anti-interference capability and resistant to power grid voltage fluctuations.
3. DC Output: 3.5 kW per output channel with adjustable output voltage: DC 200–250 V
4. Protection Functions: Short-Circuit Protection, Overtemperature Protection,
Overcurrent / Overload Protection, and Overvoltage / Undervoltage Protection
