DC power supply
Technical specifications
Input voltage
24 VDC (20.4 to 28.8 VDC)
Power consumption
Max. 30 W
Buffering upon power failure
Hold-up time > 10 ms
Protection class
Safety class III
Note
Inrush current
The device needs an inrush current of at least 4 A for 25 ms.
The peak value of the inrush current depends on the input voltage and the impedance of the
24 V source; peak currents in excess of 4 A are possible. This will not have a negative
impact on device functionality.
