TES 20 Series, 20 Watt
Features
Wide 2 : 1 Input Range
Highest Power Density
Operating Temp. Range
25C to +71C
Indefinite Short-Circuit Protection
I/O-Isolation 1500 VDC
Remote on/off
Input Filter meets EN 55022, Class A

3 Year Product Warranty
The TES 20 converter series is intended for all applications where PCB's are assem-
bled on an automated SMD production line. The light weight DIL-package allows
easy handling by pick and place machines. High efficiency allows an operating
temperature range of -40C to +71C without derating. I/O-isolation of 1'500 VDC
together with conducted noise complianceto EN 55022-A and FCC, level A makes
these converters ideal for a wide range of applications in communications, mobile
battery powered equipments and industrial systems.
