Note
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 >70°C, the
device will run into Over Temperature
Protection.
When
voltage will go into bouncing mode and will
recover
when
temperature is lowered or the load is reduced
as far as necessary to keep the device in
working condition.
3.
To ensure sufficient convection cooling,
always maintain a distance of ≥ 20mm from
fan ventilated surfaces while the device is in
operation.
4.
Depending
on
temperature and output load delivered by the
power supply, the device housing can be
very hot!
5.
If the device has to be mounted in any other
orientation, please do not hesitate to contact
info@deltapsu.com for more details.
