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

CT5.121 are the high efficiency, electronic inrush current

limitation, active input transient filter and wide

operational temperature range, the small size and other

technological design concepts.

The C-Series includes all the essential basic functions.

The CT5.121 utilizes only 2 legs of a 3-phase system

which saves wiring and installation costs. Furthermore,

this allows a smaller unit without compromising the size

of the terminals. Due to the low power consumption, an

unbalancing of the individual phases is not expected.

PHYSICAL DIMENSIONS AND WEIGHT Weight DIN-Rail Installation Clearances 500g / 1.1lb 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. 1.0 DS-CT5.

CT5.121 12V, 8A, TWO-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.

CT5.121 12V, 8A, TWO-PHASE INPUT C-Series 23.3. CHARGING OF BATTERIES The power supply can be used to charge 12V lead-acid or maintenance free batteries. Instructions for charging batteries: a) Ensure that the ambient temperature of the power supply is below 45°C b) Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge voltage. c) End-of-charge voltage 13.9V 13.75V 13.6V 13.

CT5.121 12V, 8A, TWO-PHASE INPUT C-Series 23.6. PARALLEL USE TO INCREASE OUTPUT POWER Unit A CT5.121 power supplies can be paralleled to increase the output power. This AC + power supply has no feature included which balances the load current between the power supplies. Usually the power supply with the higher DC adjusted output voltage draws current until it goes into current limitation.

CT5.121 12V, 8A, TWO-PHASE INPUT C-Series 23.8. 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. 23-3 Daisy chaining of outputs Fig.

CT5.121 12V, 8A, TWO-PHASE INPUT C-Series 23.11. 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 maximal 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.
