Abstract: An improved high voltage sensing and disabling circuit having a desensitizing feature to compensate for initial turn-on of an electrostatic spray gun is disclosed. The circuit provides a safeguard against excessive electrostatic spray gun ionizing currents, but automatically compensates for current surges caused by line charging during turn-on.
