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