DC/DC Converter THP 3 Series 3 Watt High Isolation Features I/O-Isolation Voltage of 4000VAC Clearance and Creeping Distances min. 2.0mm Basic-, Supplementary- and Reinforced Insulation for Working Voltages up to 420VDC / 300VAC Ultra wide 4:1 Input Ranges: 9-40VDC,18-80VDC and 36-160VDC Extended Operating Temp. Range -40C to 85C Input Filter meets EN55022A without ext. Components Continuous Short Circuit Protection High Reliability, MTBF>1 Mio. Hours 3 Year Product Warranty 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 transportation systems, medical equipment, instrumentation, everywhere where high basic-, supplementary- or reinforced insulation is requested to meet specific safety standards. A high efficiency allows safe operation in a temperature range of -40C to +75C at full load without derating. Full SMD-design with exclusive use of ceramic capacitors ensure a very high reliability and a long product lifetime.
