The power supply can also be used on two-phases of a three-phase-system.

Such a phase-to-phase connection is allowed as long as the supplying

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 9519 100, plastic, 180x180x165mm

Input:

230Vac

Case A:

Load:

24V, 10A; load is placed outside the box
