No Preview Available ! [ 2 YEAR WARRANTY ] BXF300 SERIES Single output NEW Product • Industry standard footprint • Adjustable output voltage with output currents of 60A • No minimum load required • 2:1 input range for battery powered applications • Undervoltage lockout (UVLO) • Overvoltage and overcurrent protection • Synchronizable and parallelable with load sharing • Overtemperature and short circuit protection • Current monitor and power good signal • Remote ON/OFF BXF300 Series high power density DC/DC converters can provide up to 60A output current and have an industry-standard footprint, measuring just 2.40 x 4.60 x 0.52 inches. The converters are equally suitable for new designs or as replacement power sources in existing equipment. BXF300 Series converters are designed specifically for redundant and distributed power systems in the computer and telecommunications sectors, but their feature-rich specifications make them suitable for a very wide range of applications. Using Bellcore 332, the MTBF is over 1,000,000 hours. Aluminium baseplate technology and four threaded M3 inserts make heatsink attachment and thermal management easy. The BXF300 Series is approved by UL, CSA and VDE.
