Notes

1.

Power supply components may degrade, or be damaged, when the power supply is continuously used outside the shaded region,

refer to the graphs shown above.

2.

If the output capacity is not reduced when the surrounding air temperature is more than the upper limit temperature, the device will

run into Over Temperature Protection. When activated, the output voltage will go into latch mode until the mains is reapplied and

the surrounding air temperature drops to its normal operating temperature.

3.

Depending on the surrounding air temperature and output load delivered by the power supply, the device housing can be very hot!

4.

If the device has to be mounted in any other orientation, please do not hesitate to contact info@deltapsu.com for more details.
