PRODUCT OVERVIEW
The SPM25 series isolated DC-DC converters
represent the next generation in Industrial Potted
Module Technology. Featuring a full 25-Watt 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 Volts (D48), ideal for industrial
applications.
Intended target markets include transportation,
medical systems, electronic test equipment, indus-
trial processing equipment, industrial applications
where power modules must meet rugged envi-
ronmental 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 & over-temperature
protection, under-voltage lockout. The input voltage
range covers the standard Industrial requirements
with a regulated output voltage and power rating
up to 25W.
Modules provide voltage isolation (basic
insulation) from input to output of up to 1600V. 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 heat sinking or
forced air cooling.
