GENERAL DESCRIPTION

The Dimension C-Series are cost optimized power

supplies without compromising quality, reliability and

performance. The C-Series is part of the DIMENSION

power supply family. The most outstanding features of

CT10.241 are the high efficiency, electronic inrush

current limitation, active input transient filter and wide

operational temperature range. The small size is

achieved by a synchronous rectification and further

technological design details.

The C-Series includes all the essential basic functions.

The devices have a power reserve of 20% included,

which may even be used continuously at temperatures

up to +45°C. Additionally, the CT10.241 can deliver 3

times the nominal output current for 10ms which helps

to trip fuses on faulty output branches.

PHYSICAL DIMENSIONS AND WEIGHT Weight DIN-Rail Installation Clearances 750g / 1.65lb Use 35mm DIN-rails according to EN 60715 or EN 50022 with a height of 7.5 or 15mm. The DIN-rail height must be added to the unit depth (117mm) to calculate the total required installation depth. See chapter 2 Fig. 21-1 Front view Fig. 21-2 Side view Jan. 2010 / Rev. 1.3 DS-CT10.

CT10.241 24V, 10A, THREE PHASE INPUT C-Series 23. APPLICATION NOTES 23.1. PEAK CURRENT CAPABILITY Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady-state current and usually exceeds the nominal output current (including the PowerBoost) The same situation applies, when starting a capacitive load. Branch circuits are often protected with circuit breakers or fuses.

CT10.241 24V, 10A, THREE PHASE INPUT C-Series 23.3. CHARGING OF BATTERIES The power supply can be used to charge lead-acid or maintenance free batteries. (Two 12V batteries in series) Instructions for charging batteries: a) Set jumper on the front of the unit into “Parallel Use” b) Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge voltage. End-of-charge voltage 27.8V 27.5V 27.15V 26.

CT10.241 24V, 10A, THREE PHASE INPUT C-Series 23.5. EXTERNAL INPUT PROTECTION The unit is tested and approved for branch circuits up to 30A (U.S.A.) and 32A (IEC). An external protection is only required, if the supplying branch has an ampacity greater than this. Check also local codes and local requirements. In some countries local regulations might apply. If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of the circuit breaker.

PARALLEL USE TO INCREASE OUTPUT POWER Unit A Fuse CT10.241 power supplies can be paralleled to increase the output power.

DAISY CHAINING OF OUTPUTS Daisy chaining (jumping from one power supply output to the next) is allowed as long as the average output current through one terminal pin does not exceed 25A. If the current is higher, use a separate distribution terminal block. Fig. 23-8 Daisy chaining of outputs Fig.

CT10.241 24V, 10A, THREE PHASE INPUT C-Series 23.13. MOUNTING ORIENTATIONS Mounting orientations other than input terminals on the bottom and output on the top require a reduction in continuous output power or a limitation in the maximum allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the power supply. Therefore, two different derating curves for continuous operation can be found below: Curve A1 Curve A2 Recommended output current.
