De-rating
Fig. 1 De-rating for Vertical Mounting Orientation
> 50°C de-rate power by 2.5% / °C
De-rating for Horizontal Mounting Orientation
> 40°C de-rate power by 2.5% / °C
Output De-rating VS. Input Voltage
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 > 50°C (Vertical)
or > 40°C (Horizontal), the device may 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 of 20mm with adjacent units
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 do not hesitate to contact
[e-mail] for more details.
 No output power de-rating across the entire
input voltage range
