DC/DC Converter TES 20 Series 20 Watt Features Wide 2 : 1 Input Range Highest Power Density Operating Temp. Range – 25°C to +71°C Indefinite Short-Circuit Protection I/O-Isolation 1500 VDC Remote on/off Input Filter meets EN 55022, Class A and FCC, Level A Industry Standard Pinout Shielded Metal Case with insulated Baseplate 3 Year Product Warranty The TES 20 converter series is intended for all applications where PCB’s are assembled on an automated SMD production line. The light weight DIL-package allows easy handling by pick and place machines. High effi- ciency allows an operating temperature range of -40°C to +71°C 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 pow- ered equipments and industrial systems.
