ARTESWN EXB50 SERIES Single output * High efficiency topology, 91% typical on EXB50-48S05 Industry standard footprint * Wide operating temperature -40C to +70C (natural convection) * 60% to 110% output trim * No minimum load * Overvoltage and overtemperature protection * Remote sense compensation * Remote on/off The EXB50 series of 50 Watt single-output isolated DC/DC converters is specifically designed to meet the power needs of low-voltage silicon. Housed in an open-frame package with an industry-standard footprint, these latest- generation converters offer efficiencies as high as 91%. The series comprises three 24V-input models with 5V, 3.3V and 2V outputs, and six 48V-input models with 12V, 5V, 3.3V 2.5V, 2.0V and 1.8V outputs. All models feature a wide input range, trimmable output voltage and a 10A current rating (except the 12V). " Distributed By: oY _ B. J.
