CVB Series Very High Frequency (VHF) Power Supplies

CVB Series

Operating at frequencies from 30MHz to 81MHz, the CVB series provides reliable VHF power into plasma and industrial processes.  CVB generators use broadband, low-“Q” amplifiers to reduce the possibility of RF system instabilities in your system. 

Performance

Comdel CVB series power supplies offer stable VHF power at frequencies from 30 to 80 MHz. Configured within Comdel's standard control and monitoring package, the CVB series offers exceptional ease of operation. RS-232 and analog controls are provided as standard; DeviceNet is optional. Synthesizer-driven, frequency agile configurations are also available on all CVB series models.
