The JLM and JLHM dc/dc converters are additions to the Powertron family and are rated at 35 and 50 W, respectively. They offer EN50155 compliance, reverse-polarity protection, 85% efficiency, and 10-ms holdup time.
The dc/dc converters accept typical railway voltages for 24-, 36-, 52-, 72-, and 110-Vdc input ranges. The fixed outputs range from 5 to 110 Vdc. The open-frame version of both products measures 115 x 85 x 22 mm. These convection-cooled systems have an operating temperature range from –25° to 75°C with no derating.
