These represent the next generation in Industrial Potted converters offer a feature/option set including: 1 x 1 x 0.41 dimensions. Module Technology. Featuring a full 25-Watt output through-hole mounting, positive or negative logic Adjustable Vout (+10% to -10%) in one square inch of board area, the SPM25 (remote on/off), over-current & over-temperature High ef ciency series isolated DC-DC converter family offers protection, under-voltage lockout. The input voltage ef cient regulated DC power for printed circuit range covers the standard Industrial requirements Positive & negative logic, remote on/off control board mounting. The 1 x 1 x 0.41 (25.4 x 25.4 x with a regulated output voltage and power rating option 10.41 mm) converter accepts a 2:1 input voltage up to 25W. Monotonic startup into pre-bias output conditions range of 36 to 75 Volts (D48), ideal for industrial Modules provide voltage isolation (basic Continuous short circuit protection applications. insulation) from input to output of up to 1600V. The Over-temperature protection Intended target markets include transportation, Operating ambient temperature range is -40C to medical systems, electronic test equipment, indus- +85C.The module delivers full output power to Over-voltage protection trial processing equipment, industrial applications +70C with no air ow. These parts are ideal for Low output ripple and noise where power modules must meet rugged envi- applications that do not require any heat sinking or Strong thermal derating characteristics ronmental requirements, high power density, and forced air cooling.
