IMX7, IMS7 Series Data Sheet 7-Watt DC-DC Converters Features Wide input voltage ranges up to 150 VDC RoHS lead-free-solder and lead-solder-exempted products are available. 5 year warranty for RoHS lead-free-solder products with temperature index -8. 10.5 1 or 2 isolated outputs up to 48 V 0.42 25.4 50.8 1.0 1500 to 2000 VAC voltage withstand test 2.0 Immunity according to IEC/EN 61000-4-2, -3, -4, -5, -6 High efficiency (typ. 84%) Input undervoltage lockout Inhibit input, adjustable output voltages Flex power: flexible load distribution on outputs Outputs no-load, overload, and short-circuit proof Operating ambient temperature 40 to +85 C Thermal protection Planar technology for best mechanical stability 2 1 case with 10.5 mm profile Description The IMX7/IMS7 Series of board-mountable 7 Watt DC-DC converters have been designed according to the latest Safety-approved to the latest edition of IEC/EN 60950-1 and UL/CSA 60950-1 industry requirements and standards. The converters are particularly suitable for use in mobile or stationary 1 applications in transport, railways, industry, or telecom, where variable input voltages or high transient voltages are 1 70/110IMX7 prevalent. Covering a total input voltage range from 8.4 V to 150 V with six different models, the converters are available with single The circuitry is comprised of integral planar magnetics. All and electrically-isolated double outputs from 3.3 up to 48 V components are automatically assembled and securely with flexible load distribution on double outputs. An inhibit soldered onto a single PCB without any wire connections. input allows remote on/off. Magnetic feedback ensures maximum reliability and repeatability in the control loop over all operating conditions. Features include efficient input and output filtering with good Careful considerations of possible thermal stresses ensure the transient and surge protection, low output ripple and noise, consistently high efficiency over the entire input voltage range, absence of hot spots, providing long life in environments, where and high reliability as well as excellent dynamic response to temperature cycles are a reality. The thermal design allows operation at full load up to an ambient temperature of 85 C in load and line changes. free air without using any potting material. For extremely high The converters provide basic insulation with SELV outputs as vibration environments the case has holes for screw mounting. for instances required in battery-supported systems, where the bus voltage may exceed the SELV limit of 60 V. The models Several options, such as open-frame, provide a high level of application-specific engineering and design-in flexibility. 70IMX7 and 110IMX7 are CE-marked.
