Server power supply DC12V distributed system

Server Power DC12V Distributed System Technical Description:

When the mains power is normal, the server power is converted to DC12V to supply power to the server motherboard, while providing float charging power to the battery. After the mains power is cut off, the battery is connected in parallel by the DC12V bus

Continue to supply power to the motherboard until the diesel generator is started and AC power is restored. Google used lead-acid batteries for power supply in the early days, but due to the high temperature inside the server, the failure rate of lead-acid batteries was high,

Later changed to lithium battery solution. The backup time of the battery is in the minute range (usually 1-3 minutes). The advantage of this solution is that it greatly simplifies the front-end power supply system of IT equipment

1. The embedded communication power system 1U-4830 adopts active power factor compensation technology, with a power factor value of 0.99.

2. The normal operating range of AC input voltage is wide up to 90-290V.

3. Adopting full bridge soft switching technology, the efficiency can reach over 92%.

4. The embedded communication power system 1U-4860 adopts non-destructive hot plugging technology, which is plug and play and can be replaced in less than 1 minute.

5. Networked design, providing multiple communication interfaces (such as RS485, dry contacts), flexible networking, limited local and remote monitoring, and unmanned operation.

6. Complete fault protection and fault alarm functions.

7. A comprehensive lightning protection design for both AC and DC sides, suitable for areas with frequent thunderstorms.

8. Ultra low radiation, adopting advanced electromagnetic compatibility design
