Sense alarm. This alarm will detect if the sense
wires have been connected to the wrong polarity.
Hardware over voltage protection. This is a
hardware OVP that is fixed at approximately
120% of the rated voltage output.
AC Fail. This alarm function is activated when a
low AC input is detected.
Fan failure. This alarm function is activated when
the fan RPMs drop to an abnormally low level.
Force Shutdown is not activated as a result of the
PSU series detecting an error. It is a function that
is used to turn the output off through the
application of a signal from the rear-panel analog
control connector when an abnormal condition
occurs.
Alarms are output via the analog control
connector. The alarm output is an isolated open-
collector photo coupler output.
Considerations
The following situations should be taken into consideration when
using the power supply.
When the power supply switch is first turned on,
an inrush current is generated. Ensure there is
enough power available for the power supply
when first turned on, especially if a number of
units are turned on at the same time.
When the load has current peaks or is pulsed, it is
possible for the maximum current to exceed the
mean current value. The PSU power supply
