Understanding Harmonic Suppression Systems

From Harmonics Limited
 

 

A typical casino will have thousands of switched-mode power supplies on-line, twenty-four hours a day, seven days a week, 365 days a year. A typical slot machine will have at least two and likely three or more. There's the SMPS for the monitor (regardless of whether it's a CRT or an LCD), the power supply for the game's logic and often a separate power supply for the bill validator. Possibly added to the mix will be a power supply for a hopper, ticket printer and/or SMIB.
