C-Line
24V, 5A, SINGLE PHASE INPUT
22.6. SERIES OPERATION
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.
22/23
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.
22.7. INDUCTIVE AND CAPACITIVE LOADS
The unit is designed to supply any kind of loads, including capacitive and inductive loads.
22.8. CHARGING OF BATTERIES
The power supply shall not be used to charge batteries. Choose power supplies of the QS-Series for charging batteries.

22.9. OPERATION ON TWO PHASES
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
below 240V

22.10. USE IN A TIGHTLY SEALED ENCLOSURE
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: 45.8°C (in the middle of the right side of the power supply with a distance of 2cm)
Temperature outside enclosure: 23.0°C
Temperature rise: 22.8K
Jul. 2015 / Rev. 2.0 DS-CS5.244-EN
All parameters are specified at 24V, 5A, 230Vac, 50Hz, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.
