Output
Output voltage Nom. DC 48 V
Adjustment range Min. 48 - 54 Vdc Guaranteed value
Max. 56 Vdc This is the maximum output voltage that can occur in the end position of the poten-
tiometer in clockwise direction due to tolerances. It is not a guaranteed value that can
be achieved. A typical value is 55 V.

1)
Extra power
The power supply is designed to support loads with higher short-term power requirements without damage
or shutdown.
The short-time duration/bonus time is controlled in hardware by an output power manager.
Extra power is available repeatedly. Detailed information can be found in the chapter on
Repeated pulse load
[

32] .
If the power supply is subjected to extra power for longer than shown in the bonus time diagram (see Fig.
Bonus time over output power [
}
14] ), the maximum output power is automatically reduced to 960 W.

The discharge current of the output capacitors is not included.
