PAC2000S12-B1 PSU
Parameter
NO TE
● MV12/MV6/SV12 overvoltage unlock mode (unlocked if any of the following conditions is met):
●
AC input is recovered after being disconnected for 15s. (In a parallel system, if output overcurrent
occurs on one PSU, recover the power after the AC input is disconnected. The PSU can be unlocked
within 2s.)
●
INSTALLED# changes from low level to high level.
●
PSON12V# changes from high level to low level.
●
IP Present# changes from low level to high level twice within 30s.
●
After PSON12V# changes to high level for more than 500 ms and then changes to low level, the PSU
can be unlocked (MV12 output overvoltage).
●
After IP PRESENT# changes to low level for more than 500 ms and then changes to high level, the PSU
can be unlocked (SV12 output overvoltage).
● MV12 output overcurrent/short circuit unlock mode (unlocked if any of the following conditions is met):
●
AC input is recovered after being disconnected for 15s. (In a parallel system, if output overcurrent
occurs on one PSU, recover the power after the AC input is disconnected. The PSU can be unlocked
within 2s.)
●
INSTALLED# changes from low level to high level.
●
PSON12V# changes from high level to low level.
●
IP Present# changes from low level to high level twice within 30s.
●
After PSON12V# changes to high level for more than 500 ms and then changes to low level, the PSU
can be unlocked (MV12 output overcurrent).
● SV12 overcurrent/short circuit unlock mode (unlocked if any of the following conditions is met):
●
AC input is recovered after being disconnected for 15s.
●
INSTALLED# changes from low level to high level.
●
If SV12 triggers overcurrent protection but does not cause PSU shutdown, IP PRESENT# changes from
low level to high level once to unlock the PSU. If SV12 triggers overcurrent protection and causes PSU
shutdown, IP PRESENT# changes from low level to high level twice within 30s.
●
After IP PRESENT# changes to low level for more than 500 ms and then changes to high level, the PSU
can be unlocked (SV12 output overcurrent).
● MV6 overcurrent/short circuit unlock mode (unlocked if any of the following conditions is met):
●
AC input is recovered after being disconnected for 15s.
●
INSTALLED# changes from low level to high level.
●
PSON12V# changes from high level to low level.
● After the PSU triggers fault protection, the MCU and I2C in the PSU can work properly.
● If the output exceeds the rated load, the output regulated voltage precision can be ignored.
● When the PSU output mode is switched from MV12 to MV6, all loads connected to MV12 will passively exit
before the output voltage drops to 9 V. Then, the PSU only connects to MV6 loads.
