*) The ripple and noise voltage mostly consist of a mains ripple with 300Hz (50Hz mains) or 360Hz (60Hz mains). The ripple and
noise voltage can be reduced by the utilization of external capacitors.
The power supply is also designed to support loads with a higher short-term current and power requirement. The
short-term duration is firmware controlle d by an output power manager. If the nominal output power is exceeded for
a certain period of time which is defined in zone A, B and C, the power supply responds with an automatic shut-down.
Pressing the reset button or cycling the input power (10s off time is required) initiates a restart attempt. If the fault has
been cleared the device will operate normally.
The short term power can be used periodically . See section 25.1 for further information.
