12V, 4.5A, SINGLE PHASE INPUT
22.12. USE IN A TIGHTLY SEALED ENCLOSURE
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: 12V, 4.5A; load is placed outside the box
Temperature inside the box: 42.8°C (in the middle of the right side of the power supply with a distance of 1cm)
Temperature outside the box: 21.7°C
Temperature rise: 21.1K
Case B:
Load: 12V, 3.6A; (=80%) load is placed outside the box
Temperature inside the box: 41.1°C (in the middle of the right side of the power supply with a distance of 1cm)
Temperature outside the box: 21.9°C
Temperature rise: 19.2K
