Power Sources Unlimited announces the TEP 75-200 Series of compact, high-power dc/dc converter modules with 75 to 240 W output power. A rugged, sealed metal case with aluminum baseplate and optional heat sink package allows full-load operation up to 60°C (140°F) with convection cooling. Other features include 2:1 or 4:1 wide input voltage ranges, efficiency up to 93%, under-voltage lockout, reverse input voltage protection, and electromagnetic interface filters. 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. Suitable applications include industry control and transportation/railway systems for onboard power distribution.
