Industrial DC/DC converter BHT 319-F4 series

enclosedsingle-outputrugged

This rugged, industrial quality DC/DC converter is designed for a long operating life at high operating temperatures. By eliminating optocouplers and electrolytic capacitors, the MTBF of the unit is greatly improved over conventional designs. The unit operates over a wide temperature range of -40ºC to 85ºC for full specification. In addition, all heat generating components are installed on aluminum heat-sink blocks which are thermally coupled to the heatsink fins and cooled by natural convection. The internal boards are conformal coated for immunity to humidity and contamination. The construction is robust and withstands high levels of shock and vibration. The input and output are filtered for low noise. Full electronic protection eliminates failure due to abnormal operating conditions, including application errors. Large design headroom and the use of components with established reliability also contribute to the long operating life of the unit. It is manufactured at our plant under strict quality control. A railway quality version of this design, the BHT 319R-F4, is also available.
