Hi, i've been doing experiments with high voltage, 2-plate capacitors that exhibit a net thrust in one direction when charged.
I was using those cheap ebay HV units that can only be on for a few sseconds and die if on for too long, so i shopped around for a mroe reliable HV source.
I ended up ordering this (it should arrive soon) :
https://www.ebay.co.uk/itm/374582175842Instructions from the seller :
1, connect the high voltage output line to the required load (high voltage electric field), the red line is the high voltage positive pole, the black line is the high voltage output negative pole; the positive and negative discharge distance should be less than the specified distance, while the power supply must be connected to the load before energizing; so as not to damage the power supply. Please pay special attention!!!
2、Close the protection circuit and rotate the protection potentiometer to the left to the off position.
3, connected to 220V AC voltage, press the power switch, the work indicator (green) lights up, while the high voltage indicator (red) lights up. At this point the power supply begins to output high voltage; adjust the voltage adjustment potentiometer to select the required voltage; for firing protection please rotate the protection adjustment potentiometer to the right (clockwise) to the high voltage indicator (red) flashing state, then to the left (counterclockwise) back to the red light is always on position, (in the process of adjustment note that the potentiometer should be rotated slowly, do not rotate too fast.) At this time, if the output side of the fire, the power supply will cut off the high-voltage output; delay 1-2 seconds to restart; can also be designed to protect the restart time according to customer requirements.
Not yet sure how to 'close the protection circuit', and also a little worried since it requires mains AC input.
Will it cause much EMI ?
Are there any other safety concerns (aside from the usual HV protocols) ?
Thanks if you can advise.
