The L series is a range of single output, high current power supplies ideally suited
to a broad range of applications. Robust performance and field proven reliability
are hallmarks of this series. Field reliability in excess of 100,000 hours has been
documented. The L series will provide stable power for any large electronic
system including telecommunication, data processing and industrial. Typical
applications include broadcast systems, ATM systems and RISC processors and
systems. Semiconductor test equipment, semiconductor and wafer processing
equipment and functional board level testers are other possible applications.
Industrial uses include applications such as laser cutting, water purification,
battery charging, machine control, large scale data logging and optical inspection
equipment. Current sharing, built-in current monitoring, voltage margining and
remote adjustment capability are standard features. Other system interface
features include AC and DC good, OVP, OCP, over temperature protection and
remote enable. Worldwide safety certifications are included.
