We have a selection of different potted & unpotted coils for the PVM500 (these coils can also be used on the DIDRIV10 and DIDRIV10HHO). Coils are rated at 40,000 V peak to peak and are end point grounded.
We have roughly calculated transformer secondary turns at the frequencies of 20 to 65 kHz for those who need to go 1pf, 10pf, 100pf and >1µfd. These are the following optionally available coils covering all ranges.
Please note that the capacitance ratings here are for the coils by themselves, and once the coils are put into a power supply (like the PVM500) the tuneable ranges will change according to the properties of the power supply -- so for the parameters of these coils operating in the PVM500, please refer to the capacitance ranges noted on the corresponding version of the PVM500.
COIL4000L: epoxy potted coil of 4000 turns for conventional (non-resonant) loads, such as when electrodes are in direct contact with the plasma gas
COIL2500S: epoxy potted coil of 2500 turns, tunes up to 25 pfd between 20 to 65 kHz
COIL2500L: epoxy potted coil of 2500 turns, a slightly larger coil able to be driven to slightly larger powers
COIL1000S: epoxy potted coil of 1000 turns, tunes 2.7 to 138 pfd between 20 to 65 kHz
COIL1000L: epoxy potted coil of 1000 turns, a slightly larger coil able to be driven to slightly larger powers
COIL560: non-potted hand wound coil of 560 turns, tunes 100 to 1000 pfd between 20 to 65 kHz
COIL200: non-potted hand wound coil of 200 turns, tunes .001 to .01 ufd between 20 to 65 kHz
COIL50: non-potted hand wound coil of 50 turns, tunes .01 to .1 ufd between 20 to 65 kHz
COIL15: non-potted hand wound coil of 15 turns, tunes .1 to >1 ufd between 20 to 65 kHz
The non-potted hand wound coils are easily modified by removing or adding turns.
