350W DC-DC Converters Operate to 85 Degrees C
At this year's electronica, Autronic will present their ACR350 series with an output power of 350 Watts. This dc-dc converter for chassis mounting is shock and vibration resistant (EN61373) and has an extended temperature range between -40 and +85 degrees C. This makes it suitable for rough and powerful application in industry, railway and transportation systems.
Both versions of the ACR350 are available with a very wide input from 14.4- to 67.2-Vdc and 43- to 154-Vdc according EN50155 (nominal voltages of 24- to 48-Vdc and 72- to 110-Vdc, respectively) and have an output voltage of 24V, other output voltages are available upon request. In spite of the very wide input range with booster technology, the ACR350 have a high efficiency of up to 94%.
The active clamping topology helps to meet the EMC requirements: The converter reach conducted emission Class B and radiated emission according to EN55011 Class A and complies with the railway specific criteria of surge, burst and ESD without additional components. Standard feature are protection against over current, over temperature and reverse polarity as well as inrush current limiting, enable, thermal warning and power good. Easy installation because of the compact design (182 x 105 x 50 mm) and new cage clamp connectors.
