20ACPO_S Series
20W - Single Output AC-DC Converter - Universal Input - Isolated & Regulated
AC-DC Converter
20 Watt
High efficiency up to 80%
Universal AC input range
(85~264VAC)
Short circuit protection (SCP)
Wide operating ambient
temperature (-25°C~70°C)
All using 105°C long life
electrolytic capacitors
The 20ACPO_S series features standard rail mounting, energy efficiency
and is highly cost-effective. The series offers stability and high noise
immunity especially for industrial control equipment, machinery and
other demanding environments for industrial equipment. This converter
offers a compact and light weight design with and standard rail installati-
on (35mm). Furthermore this series offers Easy Fuse Tripping due and a
built-in DC OK relay contact. The converter can be installed on TS-35/7.5
or TS-35/15.
