DC to DC Power Supplies (Converters)
DC-DC Converters provide 30-year operational life.
Press Release Summary:
Featuring convection-cooled design, BHT-319R-F4 Series delivers 300 W continuous output power over -40 to +85°C range without derating. Railway-quality units accept inputs of 72, 96, and 110 Vdc, while industrial-quality models accept inputs of 24, 48, 110, or 125 Vdc. Both deliver 24, 48, 72, 125 Vdc or custom output voltage. In addition to over-voltage, overload, and short circuit protection, converters include thermal shutdown with automatic recovery. Input to output isolation is 3,000 Vdc.
Original Press Release:
300W, High Temperature, High Reliability, Convection Cooled DC-DC Converters
The BHT-319R-F4 series of DC-DC converters is designed for an operational life of 30 years at high temperatures in railway and industrial environments. The convection cooled units deliver 300W continuous output power over a -40°C to +85°C temperature range without derating. By eliminating optocouplers and electrolytic capacitors, the MTBF of the units is significantly higher than in conventional converter designs.
The railway quality series meets EN50155 for electronic equipment used on railway rolling stock. They accept inputs of 72V, 96V, 110Vdc, with wide EN50155 input ranges. The units comply with EMC standard EN50121-3-2. The industrial quality series accepts an input of 24V, 48V, 110V, or 125Vdc and meet EN55022 Class A EMI, with Class B available on request. The converters also comply with EN60950-1 and related industrial standards. Both railway and industrial series deliver a 24V, 48V, 72V, 125Vdc or custom output voltage.
Electronic protection includes over-voltage, overload and short circuit protection as well as thermal shutdown with automatic recovery. Input to output isolation is 3000Vdc. Rugged construction ensures that the units withstand high levels of shock and vibration.
