The TEP-75WI series offers very powerful, insulated DC/DC-converters with an ultra-wide 4:1 input range in a robust, shielded metallic casing. These converters are suitable for a large range of applications and have been developed especially for industrial applications, where no board mounting, but instead a mounting in the casing is necessary. A chassis mounting or the mounting of a heat sink can be done quickly and simply with the help of four M3 screws. The very high degree of efficiency permits a working temperature range of up to +60 °C with natural convection cooling without a reduction of power. Other features are the adjustable output voltage, external on/off and the low-voltage cut-off. Owing to the wide input range and the reverse polarity protection, these DC/DC-converters are a relevant solution for many applications and battery-operated systems.
