Engineering Data
Output Load De-rating VS Surrounding Air Temperature
Output Load 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 exceeds its
specification as defined on Page 3 under
“Environment”, the device will run into Over
Temperature Protection. When activated,
power supply will latch off, until the
surrounding air temperature is lowered or the
load is reduced as far as necessary to keep
the device in working condition, and require
removal/re-application of input AC voltage in
order to restart.
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
for more details.
No output power de-rating for the input
voltage from 100Vac to 264Vac
