| BXF300 Series DC/DC CONVERTERS * * * * * * * * * * Single output 150-198W Wide Input DC/DC Converters 1 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. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25C unless otherwise stated SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability Set point accuracy Line regulation Load regulation Minimum load Overshoot Undershoot Ripple and noise Temperature coefficient Transient response Remote sense INPUT SPECIFICATIONS Input voltage range Input current Input current (max.)

Iout = Inom; delta Iout = 25% Iout (max), di/dt = 1A/s. Input fusing is required based on surge and maximum input current. This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. Input reflected ripple current test set-up uses a Pi filter; 220F, 12H, 100F. Start-up into resistive load. Active high remote on/off is available (standard product is active low), designate with the suffix `H' e.g. BXF300-48S3V3H. Units should be characterised within systems. External components and filtering required.
