Notes
1 Measured as per recommended set-up. 150 mV pk-pk for EXB50-
48S12J.
2 di/dt = 0.1 A/µs, Vin = 24/48 Vdc, Tc = 25 °C, load change = 0.5 lo max.
to 0.75 lo max. and 0.75 lo max. to 0.5 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 6.3 A HRC 200 V rated fuse on the 24 V
and 3.15 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 EXB50-24S2V0J model has 5.0% max. deviation and 300 µs recovery.
9 Maximum output deviation is 10% inclusive of trim.
10 Contact factory for operation at higher altitude.
11 See Application Note 113 for derating curves.
CAUTION: Hazardous internal voltages and high temperatures.
Ensure that unit is not user accessible.
Notes Continued
12 Wide operating temperature on the EXB50-24S05J is -40 ºC to +60 ºC.
13 Input transient (48 V) ETS300 132-2 ETR283.
14 100 V, 100 ms transient applies to the EXB50-24S3V3J and 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.
15 Active low remote ON/OFF available. Please add suffix '-R' to model
number e.g. EXB50-48S3V3-RJ.
16 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.
17 NOTICE: Some models do not support all options. Please contact your
local Artesyn representative or use the on-line model number search tool at
