Engineering Data

De-rating

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

>70°C,

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 of 20mm (0.78 inch) 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

info@deltapsu.com for more details.
