Power supply unit 850 W:
•
Continuous current at 100 V: ≤ 12 A
•
Continuous current at 230 V: ≤ 6 A
•
at startup ≤ 180 A for 3.6 ms
Power supply unit 700 W (2 modules, each 700 W, redundant):
•
Continuous current at 100 V: ≤ 10 A
•
Continuous current at 230 V: ≤ 5 A
•
At startup ≤ 80 A for 3.6 ms for each module
Information on the dimensioning of fuses in higher-level system circuits
A fuse that is designed for the following tripping current is integrated in the power
supply unit of the IPC.
•
Typical 8 A (for power supply unit 550 W)
•
Typical 12 A (for power supply unit 850 W)
•
Typical 10 A (for redundant power supply unit 700 W).
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.
If you connect additional devices to the higher-level power supply circuit, use the
following fuses:
•
> 8 A (for power supply unit 550 W).
•
> 12 A (for power supply unit 850 W).
•
> 10 A (for redundant power supply unit 700 W).
The tripping characteristic of the higher-level protection must take into account the
starting currents of both the IPC and the other devices.
