Bel Fuse 48IMS15-12-9C

The IMX15, IMS15, and IMY15 Series of board mountable 15 Watt DC-DC converters have 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 8.4 up to 150 V with different models, the converters are available with single and electrically-isolated double outputs from 3.3 up to 48 V externally adjustable, with flexible load distribution on double-output models. A shutdown input allows for remote on/off. Features include efficient input and output filtering and consistently high efficiency over the entire input voltage range, high reliability, and excellent dynamic response to load and line changes. The converters have been approved by CSA. 20IMS/20IMX15 and 40IMS/40IMX15 models provide supplementary insulation. Connected to a secondary circuit, these models provide SELV outputs, even if the bus voltage at the converter input exceeds the SELV-limit of 60 VDC. The 110IMY15 models provide double insulation and are CE marked. They may be connected to a rectified 110 VAC source without any further isolation barrier. The circuitry is comprised of integrated planar magnetics. All components are automatically assembled and solidly soldered onto a single PCB without any wire connection. Magnetic feedback ensures maximum reliability and repeatability in the control loop over all operating conditions. Careful consideration of possible thermal stress ensures the absence of hot spots providing long life in environments, where temperature cycles are frequent. The thermal design allows operation at full load up to an ambient temperature of 71 °C in free air without using any potting material. For extremely high vibration environments the case has holes for screw mounting.
