Notes
1 Measured as per recommended set-up. 150 mV pk-pk for EXB50-48S12J. 2 di/dt = A/µs, Vin = 48 Vdc, Tc = 25 °C, load change = lo max. to lo
max. and lo max. to lo max. 3 The EXB50 meets level A and level B conducted emissions only with external
components connected before the input pins to the converter. 4 Recommended input fusing is A HRC 200 V rated fuse on the 48 V. 5 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product. 6 Simulated source impedance of 12 µH. 12 µH inductor in series with +Vin. 7 Start-up into resistive load. 8 Maximum output deviation is 10% inclusive of trim. 9 Contact factory for operation at higher altitude. 10 See Application Note 113 for derating curves. 11 Input transient 48 V ETS300 132-2 ETR283.
12 100 V, 100 ms transient applies to the EXB50-48S3V3J models. Please add the suffix ‘R03’ to the model number e.g. EXB50-48S3V3R03J. This is also active low remote ON/OFF.
13 Active low remote ON/OFF available. Please add suffix ‘-R’ to model number e.g. EXB50-48S3V3-RJ.
14 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.
15 NOTICE Some models do not support all options. Please contact your local Emerson Network Power representative or use the on-line model number search tool at to find a suitable alternative.

CAUTION Hazardous internal voltages and high temperatures. Ensure that unit is not user accessible.
