Engineering Data
Output Load De-rating VS Surrounding Air Temperature
Output Load De-rating VS Input Voltage
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 >50
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.
Depending on the surrounding air
temperature and output load delivered by the
power supply, the device can be very hot!
4. If the device has to be mounted in any other
orientation, please contact
info@deltapsu.com for more details.
