Spray coating apparatus comprises a spray nozzle (2) and a regulation system (16) which limits the high voltage at a high-voltage electrode (10) t o a predetermined voltage value. The system also directly measures and limits th e electric spray current of the high-voltage electrode (10) to a predetermined current value. The electric spray current is limited by adjusting the high voltage a t the high- voltage electrode (10).
