The EXB250 is a new high efficiency, open frame, isolated 165 Watt converter series in an industry standard half-brick footprint. The EXB250 delivers very high output current at low voltages, and excellent useable power density for today's high end applications. The design takes advantage of open frame construction to provide a low weight, low thermal impedance baseplate design. The seven models in the series feature an input voltage range of 33 to 75VDC and are available in output voltages of 12V, 5V, 3.3V, 2.5V, 1.8V, 1.5V and 1.2V. The output voltage on each model is adjustable from 90% to 110% of the nominal value. Typical efficiencies for the models are 90% for the 3.3V, 88% for the 2.5V and 87% for the 1.8V version. The EXB250 series also has a remote on/off capability. Overcurrent and overvoltage protection features are included as standard. With full international safety approval including EN60950 (TUV Rheinland) and UL/cUL1950, the EXB250 reduces compliance costs and time to market.

1 2 di/dt = 0.1A/s, Vin = 48VDC, Tc = 25C, load change = 0.5 lo max. to 0.75 lo max. and 0.75 lo max. to 0.5 lo max. The EXB250 meets level A and level B conducted emissions only with external components connected before the input pins to the converter. See Application Note 119. Recommended input fusing is a 10A HRC 200V rated fuse. This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. Measured with no external Pi filter. Significant reduction possible with external filter. See Application Note 119. Start-up into resistive load. Active low remote On/Off is available. Standard product is active high. When ordering active low parts, designate with the Suffix '-R', e.g EXB250-48S3V3-R. When ordering 0.145" pin lengths designate with the Suffix'-N', if the product is already a '-R' suffix product then the suffix will be '-RN' When ordering 0.110" pin lengths designate with the Suffix'-K', if the product is already a '-R' suffix product then the suffix will be '-RK
