Power Supply - 24V, 5 A, 120 W, Single-phase Input Reference Manual
Operation on Two Phases
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 voltage
is below 240V
+10%
.
Ensure the wire, which is connected to the N-terminal, is appropriately fused.
Maximum allowed voltage between a phase and PE must be below 300V AC.
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
The temperature sensor inside the box is placed in the middle of the right side
of the power supply with a distance of 10 mm (0.39 in.).
The following measurement results can be used as a reference to estimate the
temperature rise inside the enclosure.
