DC/DC Converter THL 15WI Series, 15 Watt 15 Watt converter in a 1 x 1 metal package Cost efficient design Ultra wide 4:1 input voltage range: 9-36 and 18-75 VDC Operating temperature range -40 to +70 C without derating UL 62368-1 IEC 62368-1 Internal EN 55032 class A filter The THL 15WI series is Traco Power s latest addition to the existing 15 Watt DC/DC converter range. With the focus on combining cost efficiency and quali- 1 500 VDC I/O-isolation ty this isolated high performance 15 Watt DC/DC converter is suitable for many different applications. The series comes in an encapsulated, shielded 1 x 1 x Protection against overvoltage, 0.4 metal package and has a fully integrated EN 55032 class A filter. High ef- overload and short circuit ficiency up to 91% enables the converter to operate from 40C to +70C Remote On/Off and trim function without derating. All models have an ultra wide 4:1 input voltage range and precisely regulated, isolated outputs. The series meets the latest IT safety certi- Optional heatsink for increased fications (UL 62368-1) and is thus eligible for uses in mobile equipment, instru- temperature capabilities mentation, distributed power architectures in communication and industrial 3-year product warranty electronics and everywhere where cost efficiency and quality are critical fac- tors.
