To combat counterfeiting, financial institutions employ high speed scanning systems to check received bank notes to ensure fraudulent currency does not return into circulation. Bank notes that fail the criteria can even be securely shredded. These machines often operate 24 hours a day and have to be highly reliable.

A manufacturer of bank note scanners contacted its local TDK-Lambda salesperson for a 600W and a 100W 24V power supply that was both cost-effective and reliable. The RWS-B series was suggested as it met the customer’s cost targets and had a seven year warranty. The longer warranty period is supported by conservatively rated electrolytic capacitors, ensuring a long field life – even operating 24 hours a day.
