The SXN15 is a new high efficiency open frame isolated 15 Watt converter series. The first
two models in the series feature an input voltage range of 33 to 75VDC and are available in
output voltages of 5V/3.3V and 3.3V/2.5V. The output voltage on each model is adjustable
from 90% to 110% of the nominal value. Typical efficiencies for the models are 86% for the
5V/3.3V and 85% for the 3.3V/2.5V 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.
