Instructions for DC use:

a) Use a battery or similar DC source.
b) Connect +pole to L and – pole to N.
c) In case the – pole of the battery is not connected to earth, use an appropriate fuse to protect the N terminal.

Peak current capability (up to several ms)

The power supply can deliver a peak current which is higher than the specified short term current. This helps to start
current demanding loads or to safely operate subsequent circuit breakers.

The extra current is supplied by the output capacitors inside the power supply. During this event, the capacitors will
be discharged and cause a voltage dip on the output. Detailed curves can be found in chapter 25.1

Peak current voltage dips typ. from 5V to 2.4V At 6A for 50ms, resistive load
typ. from 5V to 1.0V

typ. from 5V to 0.8V

At 15A for 2ms, resistive load
At 15A for 5ms, resistive load
