Basic Power Supply 10 A
Inductive and Capacitive Loads
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 larger than 2.0 F are
connected to the output, the unit might charge the capacitor in the
HiccupPLUS mode, see
Output on page 10
.
Charging of Batteries
Do not use the power supply to charge batteries.
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

Use in a Tightly Sealed Enclosure
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.
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.
