Power Recovery
The power supply shall recover automatically after an AC power failure. AC power failure is defined to be any
loss of AC power that exceeds the dropout criteria.
loss of AC power that exceeds the dropout criteria.
3.7.14
Voltage Interruptions
The power supply shall comply with the limits defined in EN55024: 1998/A1: 2001/A2: 2003 using the IEC
61000-4-11: Second Edition: 2004-03 test standard and performance criteria C defined in Annex B of CISPR

3.7.15
Protection Circuits
Protection circuits inside the power supply cause only the power supply’s main outputs to shut down.
If the
power supply latches off due to a protection circuit tripping, an AC cycle OFF for 15 seconds and a PSON
#
cycle HIGH for one second reset the power supply.
3.7.16
Over-current Protection (OCP)
The power supply shall have current limit to prevent the outputs from exceeding the values shown in table
below. If the current limits are exceeded the power supply shall shutdown and latch off. The latch will be
cleared by toggling the PSON
below. If the current limits are exceeded the power supply shall shutdown and latch off. The latch will be
cleared by toggling the PSON
#
signal or by an AC power interruption. The power supply shall not be damaged
from repeated power cycling in this condition. 12VSB will be auto-recovered after removing OCP limit.

Over-voltage Protection (OVP)
The power supply over voltage protection shall be locally sensed. The power supply shall shutdown and latch
off after an over voltage condition occurs. This latch shall be cleared by toggling the PSON
off after an over voltage condition occurs. This latch shall be cleared by toggling the PSON
#
signal or by an
AC power interruption. The values are measured at the output of the power supply’s connectors. The voltage
shall never exceed the maximum levels when measured at the power connectors of the power supply
connector during any single point of fail. The voltage shall never trip any lower than the minimum levels when
measured at the power connector. 12VSB will be auto-recovered after removing OVP limit.

Over-temperature Protection (OTP)
The power supply will be protected against over temperature conditions caused by loss of fan cooling or
excessive ambient temperature. In an OTP condition the PSU will shutdown. When the power supply
temperature drops to within specified limits, the power supply shall restore power automatically, while the
12VSB remains always on. The OTP circuit must have built in margin such that the power supply will not
