That seems to be optimum with 60 hertz, 10K volts. Low voltage requires much lower alternation.

Sounds like you have one of the high frequency units that uses a small coil with a solid state switcher. I use a plain old transformer that runs at line frequency. Marshall:
Marshall: Then how does the fact that close to a 1:1 ratio and 150:1 ratio impact my HVAC CS product? Marshall: Perhaps some background on my power supply will help you answer: I'm pretty sure that the frequency in not 60 Htz. because a standard multimeter set to measure millamps reads a value that's nowhere close (much less as I recall) to the constant ~30 ma output that's supposed to be delivered by this unit. From what I understand, it seeks a voltage between 4000 and 10,000 volts that will deliver this amperage. If system resistance is such that the required voltage falls outside this range it cannot operate (the power supply is then put on standby -- indicated by a flashing red light -- awaiting the resistance to falls into its range. For those not experienced with forming plasmas, air resistance can change abruptly and dramatically once a gas becomes ionized), although above 10000 volts and below 15,000 volts it's supposed to generate a reduced current, but I don't think this current is sufficient to produce an arc.
