Overtemperature (intake)

An OTP warning will be issued via the PMBus interface when the air inlet exceeds 70°C;

however the power module shall not shut down until critical internal hotspot temperatures

are exceeded.

70

°C

Overtemperature (hotspots)

The unit will shut down when internal hot spot exceed the derating guide lines and

automatically recovers when the unit is cooled down. The unit will shut down due to hot spot

at ambient temperature between 55°C-60°C with main 12V at full load.

Overcurrent

For overloads (slow) over current events a 147A nominal constant current will be sustained

until the output voltage drops below 3VDC. At this point the unit shall shut down after a

1sec period and remain in that condition for 10secs. The cycle will then repeat. For severe

(short circuit) over current events the unit shall shut down within 1ms and remain in this

condition for 200ms before attempting a re-start. the unit shall attempt

10 shutdown/re-start cycles before permanently latching off. It will then be necessary to

either recycle the DC input or toggle the PSON# input.
