ENERAL
ESCRIPTION
The Dimension CD5-Series offers a range of DIN-rail
mountable DC/DC-converters in a very compact
housing.
The CD5.242 converts a 48V voltage to a 24V
voltage. The input source can be a battery, a solar
panel or any other 48V sources.
The CD5.242 includes all the essential basic functions
and has a power reserve of 20% included. This extra
power can be used continuously up to +45°C.
The output is electrically isolated from the input in a
safe way. The input is protected against reversed
voltages and contains a soft start funtion.

    CD5.242 DC/DC Converter; 24V, 5A CD–Series 8. H 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.

    CD5.242 DC/DC Converter; 24V, 5A CD–Series 25. A PPLICATION OTES 25.1. P URRENT APABILITY Solenoids, contactors and pneumatic modules often have a steady state (sealed) 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.

Ensure that the MCB is also rated for DC voltage. The following tests show which circuit breakers the DC/DC converter typically trips.
  • Page 18: Series Operation

    Instructions for parallel use: Fig. 25-6 Schematic for parallel operation Use only DC/DC converters from the same series (C-Series) or Unit A Fuse consult PULS. Input Adjust the output voltages of all power supplies to approximately the same value (±200mV). Output A fuse (or diode) on the output is only required if more than three units are connected in parallel.

    CD5.242 DC/DC Converter; 24V, 5A CD–Series 25.8. P 1+1 R ARALLEL SE FOR EDUNDANCY DC/DC converters can be paralleled for 1+1 redundancy to gain a higher system availability. Redundant systems require a certain amount of extra power to support the load in case one DC/DC converter unit fails. The simplest way is to put two DC/DC converters in parallel.
  • Page 20: Requirements For The Supplying Source

    CD5.242 DC/DC Converter; 24V, 5A CD–Series 25.10. R EQUIREMENTS FOR THE UPPLYING OURCE In certain circumstances, the input filter of the DC/DC converter can show a resonant effect which is caused by the supplying network. Especially when additional external input filters are utilized, a superimposed AC voltage can be generated on the input terminals of the DC/DC converter which might cause a malfunction of the unit.
  • Page 21: Mounting Orientations

    CD5.242 DC/DC Converter; 24V, 5A CD–Series 25.13. M OUNTING RIENTATIONS Mounting orientations other than input terminals on the bottom and output on the top requires 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 DC/DC converter.
