CLB Series Low Frequency Power Supply

Product Announcement from Comdel, Inc.

CLB Series Low Frequency Power Supply-Image

The CLB Series of Low Frequency Power Supplies provide 2500 to 12,000 Watts of power at a single frequency in the 20kHz to 2MHz band. The Turbotune™ Technology within the unit allows frequency tuning by automatically varying its output frequency +/-10% around its nominal frequency. The CLB Series of Power Supplies come with a choice of phase lock tuning or software algorithm. The unit provides forward or delivered power mode regulation, and the solid-state design provides precise and repeatable power control, ultra-stable output and low cost of ownership.

The CLB Series is designed to meet the performance demand in RF-driven plasma systems for semiconductor processing. Applications include etch, RIE, parallel plate, ICP, RF sputtering, CVD and PVD, as well as induction and dielectric heating processes in industrial systems, and solar photovoltaic applications.
