PS1111-2403-0000 26 Version: 1.0
4 Application notes
4.1 Charging batteries
Do not use the power supply to charge batteries.
4.2 Series connection
Do not connect device outputs in series for higher output voltages.
4.3 Parallel use to increase power
Do not connect devices for higher output currents in parallel.
4.4 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 permissible as long as the supply voltage is below 240V+10%.
Fig. 14: Operation on two phases
Make sure that the conductor connected to the N terminal is fused appropriately.
4.5 Use in a tightly sealed enclosure
When the power supply is installed in a tightly sealed enclosure, the temperature inside the housing is higher
than outside. In this case, the temperature inside the housing is considered the ambient temperature for the
power supply.
The power supply is positioned at the center of the housing. There are no other heat-generating elements in
the housing
The temperature sensor in the housing is positioned at the center on the right side of the power supply with a
distance of 1cm.
The following measurement results can be used as reference for estimating the temperature rise inside the
housing.
