Air Ionization device, has signaling device coupled with high voltage supply line, and has electrical pulse circuit and signal generator with proper high voltage at high voltage supply line

摘要

The device has a high voltage supply line connected to a source of high voltage and with a signaling device. The signaling device is coupled with high voltage supply line, and has an electrical pulse circuit (28) and a signal generator (38) sending a pulsed signal at the high voltage supply line (16) during a proper high voltage. The signal generator has an optical display element and is arranged as light emitting diode.
