Technical information
8.4 Technical specifications
SIMATIC IPC477D, IPC477D PRO
Operating Instructions, 11/2016, A5E31347228-AF
225
Alternating voltage supply PRO device (AC)
Input voltage 100-240 VAC (-15 % / +15 %); 47-63 Hz
1
Power failure buffering "AC FAIL" becomes active after >= 20 ms,
The power supply continues to buffer for >= 20 ms at >= 93 V
Power consumption depends on device configuration. The specified power consumption relates to
the maximum device configuration.
Note
Inrush current
The power consumption of the device is dependent on the device configuration and can be
up to 1.1
A.
The peak value of the starting current depends on the input
voltage and the impedance of
the power supply, and can be up to 50
A for < 1 ms. This will not have a negative impact on
