The total output of all voltages amounts to a max. of 850 W and depends on the temperature of the intake air inside the
device:
• Up to 40° C: 100% of 850 W, (derating 1% / K)
• As of 50° C: 90% of 850 W, (derating 2% / K)
• As of 60° C: 70% of 850 W, (derating 1% / K)
• As of 70° C: no operation permitted

Dimensioning of the fuses in the higher-level plant circuits
A fuse that is designed for a typical tripping current of 15 A is integrated in the power
supply unit of the IPC. The pulse currents during startup are also taken into account by
the "time lag" type. In the case of a fault, this fuse ensures the correct disconnection
of the device from the power supply system. It is recommended that a fuse of at least
15 A, plus the power demand of the other devices that are also supplied via this
circuit, be used for protection of the higher-level power supply circuit. The tripping
characteristic of the higher-level protection must take into account the starting
currents of both the IPC and the other devices.

The maximum power loss of the expansion cards amounts to 80 W.
It may be increased by 265 W if the power is drawn from an actively cooled
expansion card (e.g.: high-end graphics card) that emits its waste heat directly
into the ambient air and not into the interior of the device. The requirements of
the expansion card for the temperature of the intake air (inside the device) must
be observed.
