The SXN15 is a new high efficiency open frame isolated 15 Watt converter
series in an industry standard footprint. The first four models in the series
feature an input voltage range of 33 Vdc to 75 Vdc and are available in output
voltages of 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 83% for
the 1.8 V version. The SXN15 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 SXN15 reduces compliance costs and time to
market.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated

Measured as per recommended set-up. See Application Note 116 for
further details.
di/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.
The SXN15 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 further details.
Recommended input fusing is a 2 A HRC 200 V rated fuse.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
Measured with external filter. See Application Note 116 for further details.
Start-up into resistive load.
Active low remote ON/OFF is available. Standard product is active high.
Designate with the Suffix '-R' e.g. SXN15-48S05-RJ.
Operating ambient temperatures are specified at natural convection.
Higher operating temperatures are possible with increased airflow.
See Application Note 116 for further details.
Signal Line assumed < 3 m in length.
This parameter is calculated at worst case line, load, temperature and
initial settings.
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.
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.
