Over Voltage Protection (OVP)
Each output shall have individual OVP protection circuits built in and it shall be locally sensed.
The PSU shall shutdown and latch off after an over voltage condition occurs. The output
voltages are measured at the harness connectors. The voltage shall never exceed the
maximum levels when measured at the power pins of the output harness connector during any
single point of fail.

The voltage shall never trip any lower than the minimum levels when
measured at the power pins of the connector.

Over Temperature Protection (OTP)
The power supply shall be protected against over temperature conditions caused by loss of fan
cooling or excessive ambient temperature. In an OTP condition, the PSU will shut down. When
the power supply temperature drops to within specified limits, the power supply shall restore
power automatically, while the +5VSB remains always on. The OTP trip level shall have a
minimum of 4
cooling or excessive ambient temperature. In an OTP condition, the PSU will shut down. When
the power supply temperature drops to within specified limits, the power supply shall restore
power automatically, while the +5VSB remains always on. The OTP trip level shall have a
minimum of 4
°
C of ambient temperature hysteresis, so that the power supply will not oscillate
on and off due to temperature recovery condition.

Addressing
The power supply device address locations are shown below.
For redundant systems, there are
two signals to set the address location of the power supply once it is installed in the system;
Address0 and Address1.
Address0 and Address1.
For non-redundant systems, the power supply device address
locations should align with the Address0/Address1 location of 0/0.
