Product Description
The PAC3000S12-T1 supports an AC input of 90 V
to 264 V and a DC input of 180 V to 300 V. The PSU
provides one output and supports three output
modes, that is, MV12, SV12 and MV6. The rated
output power is 3000 W. The PSU supports hot
swap, current sharing, parallel connection (1+1 or

● During the isolation process for output overvoltage protection failure, the MV12 busbar voltage should not
be lower than 11.4 V DC.
● The current share bus is used for active current sharing (I-MON).
● Test the current sharing imbalance only at room temperature.
● 1+1 parallel system: When the total load is less than or equal to the rated load of a single PSU, the current
sharing formula is [I – (I1 + I2)/2]/(I1 + I2) x 100%.
When the total load is greater than the rated load of a single PSU, the current sharing formula is
[I – (I1 + I2)/2]/IN x 100%, where IN is the rated current of a single PSU.
● In a 2+2 parallel system, the current sharing formula is as follows on the premise that the 1+1 current
sharing requirements are met:
Max [Max(I, I2, I3, I4) – Ave(I1, I2, I3, I4), Ave(I1, I2, I3, I4) – Min (I1, I2, I3, I4)]/IN x 100%, where IN is the rated
current of a single PSU.
