Technical specifications

RF Generator Specifications Circuit type: inductively feedback self-oscillation circuit, coaxial cable transmission, matched tuning, power feedback close-loop auto-controlWorking frequency: 40MHz±0.05% Frequency stability: <0.1%Power output: 800W-1200WPower output stability: <0.3%Intensity of electromagnetic leakage: electric filed intensity in 30cm distanceto the body: E:<2V/mHigh Frequency BoxHigh Frequency Box excites very stable plasma torch by exploiting the inductively feedback self-oscillation circuit. The circuit is transmitted by coaxial cable,matchingly tuned and implements close-loop auto-control by means of power feedback (National Patented Invention). Industrial argon can be used in this kind of generator, which not only makes the lighting the ICP torch easy butalso saves the cost of highly purified argon. Match boxThe high performance match box is composed of vacuum ceramic adjustable capacitors and gas adjustable capacitors, which allows it to reach the best match state and achieve maximum effective output on load coils. Directional couplerThe stability of power output is achieved by controlling the anode voltage of oscillation valve after the power signals are sent out of the directional coupler and get amplified by the amplifier.
