250-W, high-density DC/DC converter targets rugged industrial environments

The standard stock versions have two output terminals: a Redundant via a built-in redundancy diode, and a Direct, which bypasses the redundancy diode.    They can be used in Redundant or Direct operation, depending on application requirements.  On the Redundant output, these converters can be used for redundant parallel or N+1 operation. The Direct output can be used for monitoring, precision regulation or to achieve higher efficiency.   The 125 Vdc input version (90 V to 145 Vdc standard range) is available with 24 Vdc or 48Vdc standard outputs.  A Form C output fail alarm is included in this design.

The calculated MTBF of the unit is above 150, 000 hours at 45 degrees C, with demonstrated figures expected to be higher, which is the case for the company’s other products. These rugged converters meet EN61373/IEC61373 shock and vibration standards; additional ruggedizing and conformal coating are available for operation in extreme environments. Other features include inrush current limiting, reverse polarity protection and rectangular, continuous current limiting with short-circuit protection (no hiccup). Thermal protection is by built in thermostat with self-resetting. Efficiency is 85% or higher, depending on the output configuration.


Standard versions of the BAP 190 series are priced in the $182 range in quantities of 100.
