The Traco Power TEP 75-200 Series of high power DC/DC converter modules are ultra-compact and high power, with output power from 75W up to 240W. Packaged in a rugged, sealed metal case with aluminum baseplate and optional heat sink that allows full load operation up to 60°C with convection cooling. Featuring 2:1 or 4:1 wide input voltage ranges, high-efficiency up to 93%, under-voltage lockout, reverse input voltage protection, input protection filter and a 3-year product warranty.
Additional features include EMI Filter to meet EN 55022 Class A, detailed application notes, and additional filtering component recommendations to meet EN 55022 Class B conducted. These modules can be mounted to a printed circuit board, with or without a heat sink, chassis mounted screw terminal connections with filter, and DIN-Rail mount. Typical applications are in telecom/datacom, industry control and transportation/railway systems for on board power distribution.
