• High efficiency topology, 91% typical on EXB50-48S05J
• Industry standard footprint
• Wide operating temperature -40 °C to +70 °C
(natural convection)
• 60% to 110% output trim
• No minimum load
• Overvoltage and overtemperature protection
• Remote sense compensation
• Remote ON/OFF
• Available RoHS compliant
The EXB50 series of 50 Watt single-output isolated dc-dc converters are 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 24 V input models with 5 V,
3.3 V and 2 V outputs, and six 48 V input models with 12 V, 5 V, 3.3 V 2.5 V, 2 V and
1.8 V outputs. All models feature a wide input range, trimmable output voltage and a
10 A current rating (except the 12 V). Remote sense and remote ON/OFF facilities are
included as standard, and the converters are comprehensively protected against
overcurrent, overvoltage and overtemperature conditions.

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 EXB5048S3V3J 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
http://www.artesyn.com/powergroup/products.htm to find a suitable
alternative.
Measured as per recommended set-up. 150 mV pk-pk for EXB5048S12J.

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.
