DC/DC Converters THD 12WI Series, 12 Watt Features ◆ Highest power density: 12W in DIP 24 package! ◆ Ultra-wide 4:1 input range ◆ Very high efficiency up to 85% ◆ I/O isolation 1500V ◆ Input filter meets EN 55022A without ext. components ◆ Remote On/Off ◆ Under voltage lock-out circuit ◆ Shielded metal case with insulated baseplate ◆ Continuous short-circuit protection ◆ Operating temp. range –40°C to +85°C ◆ Lead free design, RoHS compliant ◆ 3-year product warranty The THD-12WI series is a range of high performance, isolated 12W dc/dc converter modules featuring ultra wide 4:1 input voltage ranges in a DIP-24 package with industry-standard footprint. Overload and overvoltage protection as well as remote On/Off are included as standard. Built-in filters for both input and output minimizes the need of external filtering. Full SMD-design with exclusive use of ceramic capaci- tors guarantees a high reliability and long product lifetime. Typical applications for these converters are industrial electronics, instrumentation, data communication sys- tems and battery operated equipment with limited space available on the PCB.
