GENERAL DESCRIPTION

The Dimension CD-Series offer DIN-rail DC/DC converters

in the 92-120W output power range in a very compact

housing. These DC/DC converters are allowed to run

with a battery or similar sources or can also be used to

refresh and stabilize the 24Vdc on the end of long cable

runs. The basic units include all the essential basic

functions while the -S1 version is equipped with quick-

connect spring clamp terminals, a DC-OK-contact which

monitors the output and an input-low-relay-contact.

The –L1 version additionally fulfills the NEC Class 2

requirements. All devices except the CD5.241-L1 have a

PowerBoost of 20% incorporated. This extra power can

even be used continuously up to +45°C.

HOLD-UP TIME The input side of the DC/DC converter is equipped with a bulk capacitor which keeps the output voltage alive for a certain period of time when the input voltage dips or is removed. The bulk capacitor can be discharged by loading the DC/DC converter on the output side or through a load which is parallel to the input. There is no protection in the DC/DC converter which prevents current from flowing back to the input terminals.

DC-OK RELAY CONTACT This feature is only available on the model CD5.241-S1 and monitors the output voltage, which is produced by the DC/DC converter itself. It is independent of a back-fed voltage from a unit which is connected in parallel to the DC/DC converter output. It is a “Normally Open” contact. Contact closes Contact opens As soon as the output voltage reaches the adjusted output voltage.

PHYSICAL DIMENSIONS AND WEIGHT Weight DIN-Rail Installation Clearances 450g / 0.99lb 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 (102mm) to calculate the total required installation depth. See chapter 2 Fig. 22-1 Front view Fig. 22-2 Side view Oct 2009 / Rev. 1.3 DS-CD5.

CD5.241-S1 DC/DC Converter 24V, 5A CD-Series 24. APPLICATION NOTES 24.1. 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.

(Two 12V batteries in series) Instructions for charging batteries: a) Ensure that the ambient temperature of the DC/DC converter is below 45°C b) Do not use DC/DC converters in mounting orientations other than the standard mounting orientation (input terminals on the bottom and output terminals on top of the unit).

CD5.241-S1 DC/DC Converter 24V, 5A CD-Series 24.7. PARALLEL USE TO INCREASE OUTPUT POWER Unit A The DC/DC-converter can be paralleled to increase the output power. There are no feature included which balances the load current between the DC/DC converters. Therefore some restrictions and limitations apply. The DC/DC converter with the higher adjusted output voltage draws current until it goes into current limitation.

CD5.241-S1 DC/DC Converter 24V, 5A CD-Series 24.9. DAISY CHAINING OF OUTPUTS Daisy chaining (jumping from one DC/DC converter 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. 24-4 Daisy chaining of outputs Fig.

CD5.241-S1 DC/DC Converter 24V, 5A CD-Series 24.12. 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 max. allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the DC/DC converter. Therefore, two different derating curves for continuous operation can be found below: Curve A1 Curve A2 Recommended output current.
