Power supplies of the same type can be connected in series for higher

output voltages. It is possible to connect as many units in series as needed,

providing the sum of the output voltage does not exceed 150Vdc. Voltages

with a potential above 60Vdc are no longer SELV and can be dangerous.

Such voltages must be installed with a protection against touching.

Earthing of the output is required when the sum of the output voltage is

above 60Vdc.

Avoid return voltage (e.g. from a decelerating motor or battery) which is

applied to the output terminals.

Keep an installation clearance of 15mm (left / right) between two power supplies and avoid installing the power

supplies on top of each other. Do not use power supplies in series in mounting orientations other than the standard

mounting orientation (input terminals on bottom of the unit).

Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.

The unit is designed to supply any kind of loads, including capacitive and inductive loads.

The power supply can also be used on two-phases of a three-phase-system. A

phase-to-phase connection is allowed as long as the supplying voltage is

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
