1. Power supply components may degrade, or
be damaged, when the power supply is
continuously used outside the shaded region,
refer to the graph shown in Fig. 1.
2. If the output capacity is not reduced when the
surrounding air temperature
specification as defined on Page 3 under
“Environment”, the device will run into Over
Temperature Protection. When activated, the
output voltage will go into bouncing mode and
will recover when the surrounding air
temperature is lowered or the load is reduced
as far as necessary to keep the device in
working condition.
3. In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance as recommended in the
safety instructions while the device is in
operation.
4. Depending on the surrounding air temperature
and output load delivered by the power
supply, the device can be very hot!
5. If the device has to be mounted in any other
orientation, please contact info@deltapsu.com
