Automatic vending and gaming is a billion dollar industry with an increasing variety of innovative machines allowing people to enjoy maximum convenience, worldwide. It is possible to serve the public 24 hours a day with goods ranging from a cold beverage to an iPod, and with services ranging from cashless payment at a gas station to full e-banking at drive-in ATMs. Also with automatic gaming machines Schaffner products ensure good entertainment without unwanted interference.
 
Modern machines work with a large variety of electronic devices like coin validators, money scanners, card readers, power supplies, lighting units, displays, motor drives and control units, internet connections, cooling or heating systems, printers and so on. With the increasing functionality of these modern “supermachines” mainly achieved by more elec­tronic components inside, there are also higher requirements for electromagnetic compatibility (EMC).
 
To protect the sensitive electronics from malfunction and to guarantee a trouble-free operation in spite of the more complex technology, measures are needed to fulfill EMC standards, to ensure mains power quality and to suppress mains disturbances.
