2 YEAR WARRANTY

SXN15 Series

Single output

•High efficiency topology, 87% typical at 5 V

•Wide operating temperature, up to and exceeding 70 ˚C

(natural convection)

•90% to 110% output trim

•No minimum load

•Overvoltage protection

•Remote ON/OFF control

•Available RoHS compliant

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

further 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 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.

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 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. SXN15-48S05-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 Signal Line assumed < 3 m in length.

11 This parameter is calculated at worst case line, load, temperature and

initial settings.

12 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.
