The SPM25 series isolated DC/DC converters represent the next generation in Industrial Potted Module Technology. Featuring a full 25 W output in one square inch of board area, the SPM25 series isolated DC/DC converter family offers efficient regulated DC power for printed circuit board mounting. The 1˝ x 1˝ x 0.41˝ (25.4 x 25.4 x 10.41 mm) converter accepts a 2:1 input voltage range of 36 to 75 V (D48), ideal for industrial applications. Intended target markets include transportation, medical systems, electronic test equipment, industrial processing equipment, industrial applications where power modules must meet rugged environmental requirements, high power density, and where isolated output voltages are required. These converters offer a feature/option set including: through-hole mounting, positive or negative logic (remote on/off), over-current and over-temperature protection, and under-voltage lockout. The input voltage range covers the standard industrial requirements with a regulated output voltage and power rating up to 25 W. Modules provide voltage isolation (basic insulation) from input to output of up to 1600 V. The operating ambient temperature range is -40°C to +85°C. The module delivers full output power to +70°C with no airflow. These parts are ideal for applications that do not require any heatsinking or forced air cooling.
