AC to DC Power Supply HVDC-DC Module

The rated output power is 900 W. The PSU is hotswappable, equalizes current, and supports 1+1 or 2+2 parallel connection.
The PSU supports PMBus communication, and sends the PSU information to the system to facilitate monitoring and management.

Applications: Server
The PSU can withstand an input voltage of 318 V AC for 48 hours (non-working state is acceptable).
The inrush current should meet the requirements in ETSI EN 300 132-3.
When testing the maximum input current, ensure that the voltage of the power input port meets the requirement and that the output is 900 W.
Current Share Design Requirements
1. Supports 1+1 or 2+2 mode. Current sharing only in MV12 mode.
2. The total load at startup in parallel operation scenarios should be less than the rated load of a single PSU.
3. When PSUs work in 1+1 or 2+2 mode, if one of the PSUs works in MV6 mode and other PSUs work in MV12 mode, the PSUs should work properly without ffc each other.
4. In scenarios where ff PSUs are not installed together, the I-MON signals of the two PSUs should not ffc the normal operation of the PSUs when they are directly connected.
5. Current sharing imbalance only in the normal temperature condition.
