1U Rack Mount DC to DC Switching Power Supplies
DC-DC converter, also known as a DC-DC converter, is a circuit or electromechanical device that converts electrical energy into DC power of different voltages. Its power range can range from very small (small batteries) to very large (high-voltage power conversion). Some DC-DC converters have the same reference point for their output voltage and input voltage, while others have their output voltage isolated from the input voltage.

Frequently Asked Questions (FAQ)
What is the conversion efficiency of the rectifier module?
The rectifier module utilizes full bridge soft switching technology, allowing the system efficiency to reach above 92%, and up to 93% under a 220Vac input condition.
What is the input voltage range supported by this DC-DC converter?
The module supports a wide normal operating AC input voltage range from 90V to 290V. The system input voltage range spans from 110Vdc to 410Vdc.
Does the system support active power factor correction?
Yes, the rectifier module adopts advanced active power factor compensation technology, which achieves a power factor of up to 0.99 for optimized energy use.
What are the mechanical dimensions of this 1U rack mount power system?
The standard dimensions of the unit are 482.6mm in width, 238mm in depth, and 43.6mm in height (482.6mm W × 238mm D × 43.6mm H), making it suitable for standard 1U rack installations.
How does the system output current behave under lower input voltages?
For input voltages between 170VAC and 285VAC, the system operates normally. If the input voltage drops below 170VAC, the output current operates in a derating manner to ensure system safety.
Can a battery pack be connected in parallel with the DC output?
Yes, the positive and negative poles of the battery pack can be connected in parallel with the DC output of the rectifier module, ensuring consistent polarity.
