Single power supply (400 W):
• Continuous current at 100 V: ≤ 6 A
• Continuous current at 230 V: ≤ 3 A
• At startup ≤ 80 A for 3.6 ms
Redundant power supply (350 W):
• Continuous current at 100 V: ≤ 5 A
• Continuous current at 230 V: ≤ 2.5 A
• at startup ≤ 210 A for 1.65 ms for each module
Information on the dimensioning of the fuses in the higher-level plant circuits
A fuse that is designed for the following tripping current is integrated in the power supply unit of
the IPC:
• typical 6.3 A (with single power supply 400 W and redundant power supply 350 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 sys-
tem.
Insert the following fuses for the device:
• > 6.3 A (with single power supply 400 W and redundant power supply 350 W).
If you connect additional devices to the higher-level power supply circuit, take into account their
total power requirement.
The tripping characteristic of the higher-level protection must take into account the starting cur-
rents of both the IPC and the other devices.
50 to 60 Hz, min. 47 Hz to max. 63 Hz, sinusoidal
Single power supply (400 W):
20 ms
≤ 10 events/h; recovery time ≥ 1 s
Redundant power supply (350 W):
20 ms
≤ 10 events/h; recovery time ≥ 1 s
Single power supply (400 W), with maximum configuration and 230 W secondary:
• ≤ 260 W; with 88% efficiency
Redundant power supply (350 W),
with maximum configuration and 230 W secondary:
• ≤ 270 W with 85% efficiency
Single power supply (400 W):
• 260 W = 260 J/s = 0.25 BTU/s
Redundant power supply (350 W):
• 270 W = 270 J/s = 0.26 BTU/s
