24IMX70-24-24-0G

The IMX70 Series of board-mountable 70 Watt DC-DC converters has been designed according to the latest industry requirements and standards. The converters are particularly suitable for use in mobile or stationary applications in transport, railways, industry, or telecommunication, where variable input voltages or high transient voltages are prevalent. Covering a total input voltage range from 14.4 V up to 154 V with 3 different models, the converters are available with one or two electrically isolated outputs from 5 V to 48 V, externally adjustable and with flexible load distribution. A shutdown input allows remote converter on/off. Features include consistently high efficiency over the entire input voltage range, high reliability, and excellent dynamic response to load and line changes. The converters are designed according to the international safety standards IEC/EN/UL 60950-1 2nd Edition. The converters 24IMX70 and 40IMX70 exhibit basic insulation for the specified input voltage, whereas the converters 110IMY70 have reinforced insulation. The circuit is comprised of 2 planar magnetic devices. The components are automatically assembled and securely soldered onto a single PCB without any wire connection. Magnetic feedback ensures maximum repeatability in the control loop over all operating conditions and best reliability. Careful consideration of possible thermal stress ensure the absence of hot spots, such providing long life in environments, where temperature cycles are present. The thermal design without using any potting material allows operation up to an ambient temperature of 70°C in free air and up to 100°C with forced cooling. For extremely high vibration environments the case has holes for screw mounting.
