PAC2000S12-B1 PSU
5.1 Active/Standby (Hot Standby) Power Supply
If PSUs work in parallel, the PSU with an output setting voltage of 12.3 V is the active PSU and the
PSU with an output setting voltage of 12.05 V is the standby PSU.
●
Only hot standby is supported for MV12 output.
●
If PS_CONTROL (CEh) bit 7 is set to 1, the output voltage of the standby PSU is set to 12.05 V
by VOUT_COMMAND (21h).
