C-Line

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.

23/24

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).

(see notes)

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 shall not be used to charge batteries. Choose power supplies of the QS-Series for charging batteries.

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 9516 100, plastic, 110x180x165mm

Load:

24V, 4A; (=80%) load is placed outside the box

Input:

230Vac

Temperature inside enclosure:

46.3°C (in the middle of the right side of the power supply with a distance of 2cm)

Temperature outside enclosure: 23.3°C

Temperature rise:

23.0K
