The THP-3 series is a new range of high performance 3W DC/DC converters in
a low profile DIL-24 package with standard industry pin-out. The very high I/O-
isolation system of these converters and input voltages up to 160 VDC make this
product the best choice for many demanding applications in railroad and transpor-
tation systems, medical equipment, instrumentation, everywhere where high basic-,
supplementary- or reinforced insulation is requested to meet specific safety stan-
dards. A high efficiency allows safe operation in a temperature range of –40°C to
+70°C at full load. Full SMD-design with exclusive use of ceramic capacitors ensure
a very high reliability and a long product lifetime.
