Power Supply - 24V, 10 A, 240 W, Three-phase Input
Use in a Tightly Sealed Container
When the power supply is installed in a tightly sealed enclosure, the temperature
inside the enclosure is higher than outside. In such situations, the inside
temperature defines the ambient temperature for the power supply.
In the following test setup, the device is placed in the middle of the box, no other
heat producing items are inside the box. The load is placed outside the box.
The temperature sensor inside the box is placed in the middle of the right side of
the power supply with a distance of 1 cm (0.39 in.).
