14.3 Integrated DC power supply
SIMATIC IPC427C
96
Operating Instructions, 04/2009, A5E02414743-01
14.3
Integrated DC power supply
Technical specifications
Input voltage
24 VDC (19.2 to 28.8 VDC)
Power consumption 1)
max. 72 W
Power failure buffering
Hold-up time > 15 ms
(after > 5 ms DC_FAIL becomes active)
Maximum continuous output power 1)
60 W
Degree of protection
IP 20
Protection class
Safety class I (A protective conductor must be
connected to the device)
1) The performance specifications apply to the power supply components and the IPC427C device.
Note
Inrush current
A minimum of 4.5 A inrush current for 15 ms is required for starting the IPC427C.
The peak value of the startup current depends on the input voltage and the impedance of the
24V source: Peak values of more than 4.5 A are possible. This will not inhibit the operation
of the IPC427C.
