The unit is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large capacitors,
such as EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance > 1F are connected to the output,
the unit might charge the capacitor in the Hiccup

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

NCLOSURE
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 Typ IP66 Box PK 9519 100, plastic, 180x180x165mm
Load:
24V, 16A; (=80%) load is placed outside the box
Input:
230Vac
Temperature inside enclosure: 51.9°C (in the middle of the right side of the power supply with a distance of 2cm)
Temperature outside enclosure: 25.6°C
Temperature rise:
