MiniLine-2

When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher

than outside. In such situations, the inside temperature defines the ambient temperature for the power supply.

The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.

The power supply is placed in the middle of the box, no other heat producing items are inside the box

Enclosure:

Rittal Type IP66 Box PK 9510 100, plastic, 130x130x75mm

Input:

230Vac

Case A:

Load:

5V, 3A; load is placed outside the box

26.0°C

Temperature rise:

12.2K

Case B:
