□ionerusionj CD-Series CD10.242DC/DC Converter 48V/24V, 10A, 240WDC/DC Converter ■ 48V input voltage ■ Isolated 24V output voltage ■ 20% output power reserves (PowerBoost) ■ Full power between -25°C and +60°C ■ Minimal inrush current surge ■ Reverse input polarity protection ■ Parallel use for high power needs The CD10.242 is a DIN rail mountable DC/DC converter of the highly reliable DIMENSION series. It provides a floating, stabilized and galvanically separated SELV/PELV output voltage of 24Vdc with 48Vdc on the input. The efficiency of 94% and a slim design are cost- and space-saving. The devices also offer PowerBoost: Power reserves of 20%, which may even be used continuously at temperatures up to +45°C. For even higher power needs, multiple devices can be connected in parallel. At any time, a DC OK LED and a signal contact are informing about the status of the device. High immunity to transients and power surges as well as low electromagnetic emission makes this DC/DC converter suitable for nearly every situation.

Requirements for the Supplying Source 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. Therefore, additional input filters are not recommended. To avoid the resonant effects, the minimal resistance of the supplying network which depends on the inductance of the input network, shall be above the boundary curve in Fig....

Dlfinerusioru CD-Series_DC/DC Converter 48V/24V, 10A, 240W | 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. If prevention is needed, an external diode should be used. At no load, the hold-up time can be up to several...
