DC/DC Converter TEL 12WI Series, 12 Watt Ultra compact 12 Watt converter in DIP-16 metal casing Highest power density of 3,61W/cm3 6-side shielded metal case with insulated baseplate Wide 4:1 input voltage range UL 62368-1 IEC 62368-1 High efficiency (up to 88%) for low thermal loss The TEL 12WI is a 12 Watt DC/DC converter series which comes in an ultra compact DIP-16 metal package. The design purpose was to miniaturized low Operating temperature range -40C to power DC/DC converters to the maximum without sacrificing high efficiency. +88C They solidify the new standard for power density with 3,61 W/cm3 and effec- tively double the power density compared to 12 Watt converters in DIP-24 Built-In EN 55032 class A filter package. The TEL 12WI and offers a wide 4:1 input voltage range and features Protection against short circuit a high efficiency of up to 88% which enables an operation temperature of up to +65C at full load and up to 85C with 50% load. The converters also have an 3-year product warranty internal input filter to comply with conducted emission standard EN 55032 class A. Overall they feature an economical solution for space critical and cost sensitive applications in instrumentation, IT and industrial electronics.
