The EXB250 delivers very high output current at low voltages, and excellent useable power density for todays 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 s - capability. Overcurrent and overvoltage protection features are included as standard. cWAN US TUV With full international safety approval including EN60950, (TUV Rheinland) and UL/cUL1950, the EXB250 reduces compliance costs and time to market. 2 YEAR WARRANTY: All specifications are typical at nominal input, full load at 25C unless otherwise stated SPECIFICATIONS OUTPUT SPECIFICATIONS EMC CHARACTERISTICS Voltage adjustability 90% to 110% Conducted emissions EN55022 (See Note 2} Level A ee Hy N55022 (See Note 2) Level B Set point accuracy 7 _ +1.6% max. | Immunity: Line regulation 1V2 model +0.2% max.
