The SXE15 is a new high efficiency open frame isolated 15 Watt converter series in
an industry standard footprint. All models in the series feature an input voltage range
of 33 Vdc to 75 Vdc and are available in output voltages of 12 V, 5 V, 3.3 V, 2.5 V
and 1.8 V. The output voltage on each model is adjustable from 90% to 110% of the
nominal value. Typical efficiencies for the models are 87% for the 5 V, 86% for the
3.3 V, 85% for the 2.5 V and 12 V and 83% for the 1.8 V version. The SXE15 series
also has a remote ON/OFF capability with active high or active low logic.
Overcurrent and overvoltage protection features are included as standard. With full
international safety approval including EN60950 and cUL1950, the SXE15 reduces
compliance costs and time to market.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated

1Measured as per recommended set-up. See Application Note 116 for details.
2di/dt = 0.1 A/µs, Vin = 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.
3The SXE15 meets level A and level B conducted emissions only with
external components connected before the input pins to the converter.
See Application Note 116 for details.
4Recommended input fusing is a 2 A HRC 200 V rated fuse.
5This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
6Measured with external Pi filter. See Application Note 116 for further details.
7Start-up into resistive load.
8Active low remote on/off is available. Standard product is active high.
Designate with the Suffix ‘-R’ e.g. SXE15-48S05-RJ.
9Operating ambient temperatures are specified at natural convection.
Higher operating temperatures are possible with increased airflow.
See Application Note 116 for further details.
10 SXE15-48S12J below 0.2 A loading. OVP is TVS and 17 V typical.
11 Signal line assumed < 3 m in length.
12 A 5% minimum load is required to maintain the output voltage regulation
over all operating conditions for the SXE15-48S12J.
13 This parameter is calculated at worst case line, load,
temperature and initial settings.
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 Artesyn representative or use the on-line model number search tool at
