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