A Series
15W, 30W, 50W, 100W, 150W
The SWA series is made up of general-purpose, single-output power supply
units for world-wide use. Input voltages from 85 to 264 V may be used with
no manual voltage selection required. The series has five advanced-design
models ranging from 15 to 150 W. The 100 W and 150 W models are
equipped with Power Factor Correction circuits, and take into account the
IEC 555 Part 2 regulations on harmonic currents.
FEATURES
Wide input voltage range
High power factor of 0.95 achieved using a Power Factor Correction IC
(100 W, 150 W)
New Barrierless Transformer technology for reduced size
MOSFET-based main switching circuit for high efficiency
Designed to meet UL, CSA, and VDE safety standards
The 100 W and 150 W models are equipped with Power Factor Correction
circuits.

Note 1: Rated input/output conditions means that the switching power supply is operated under the rated input voltage, rated frequency, rated output voltage, rated output current, and
at an ambient temperature of 25C and 60% humidity.
Note 2: At cold start. (More current may flow at restart.)
Note 3: All output characteristics are measured at a point 5 cm from the output connector, with a 63 V 47 F electrolytic capacitor attached at that point.
Note 4: Ripple noise is measured with a 100 MHz oscilloscope, using a 1:1 probe.
Note 5: At room temperature and normal humidity.
