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 >40°C (115Vac)

or >50°C (230Vac), 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
