264W Wide Input DC/DC Converters 1
Industry standard footprint Adjustable output voltage with output currents of 80A No minimum load required 2:1 input range for battery powered applications Undervoltage lockout (UVLO) Overvoltage and overcurrent protection Synchronisable and parallelable with load sharing Overtemperature and short circuit protection Current monitor and power good signal Remote ON/OFF Available RoHS compliant
BXF400 Series high power density DC/DC converters can provide up to 80A output current and have an industry-standard footprint, measuring just 2.40 x 4.60 x 0.52 inches. These converters have the highest output current rating of any comparably-sized products on the market, are equally suitable for new designs or as replacement power sources in existing equipment. BXF400 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 BXF400 Series is approved by UL, CSA and VDE.
All specifications are typical at nominal input, full load at 25C unless otherwise stated

Measured with 10F tantalum capacitor and 1F ceramic capacitor across the output. 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. Units should be characterised within systems. External components and filtering required. The `J' suffix indicates that these parts are Pb-free (RoHS 6/6) compliant. TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your local sales representative for details..
