DC/DC Medical Converter THB 3 Series, 3 Watt Supplementary and reinforced insulation I/O isolation 4800 VACrms rated for 1000 Vrms (1410 Vpk) working voltage Medical safety to ES 60601-1 and IEC/EN 60601-1 3rd edition, 2 x MOOP Isolation test voltage 6000 Vpk ES 60601-1 IEC 60601-1 UL 60950-1 IEC 60950-1 Wide 2:1 input voltage ranges The THB 3 series is a range of high performance, regulated DC/DC converters Extended operating temperature range in a DIP-24 plastic package. A reinforced I/O-isolation system and a wide 2:1 40C to 85C max. input voltage range make this product the best choice for many demanding ap- plications like transportation systems, industrial controls, medical equipments, Input filter meets EN55022, class A instrumentations, everywhere where high basic-, supplementary- or reinforced Continuous short-circuit protection insulation is required to meet requested safety standards. A high efficiency al- lows safe operation in a temperature range of 40C to +85C. Other features High reliability of this product are over voltage protection and internal EMI-input filter to meet 3-year product warranty EN 55022, class A without additional components. Full SMD-design with exclu- sive use of ceramic capacitors ensure a very high reliability and a long product lifetime.
