RECOM Switching Regulator, 6W Power Rating, 97% Maximum Efficiency - R-78AA-0.5 Series - R-78AA12-0.5SMD


Cut energy waste out of your equation with this switching regulator from RECOM. It converts up to 97% of the input voltage, so it minimises heat and keeps a cool head while efficiently powering your components. That means there's no need to bring a heatsink to this party. The unit has integrated short-circuit protection and automatically resets after tripping, so shrugs off supply issues to downsize downtime. It makes quick work of source conversion by starting up in just 50ms. Thanks to insulating epoxy resin potting and plastic housing, you can trust this regulator to effectively protect you against electrical hazards.

• Low maximum ripple voltage of 40mV, so it produces minimal electrical noise
• Output voltage accurate to ±3%, ensuring you get a reliable power source
• Wide input voltage range between 15 and 32V DC to work with many electrical supplies
• Compact body measurements of 15.3 (L) x 9.6 (W) x 8.8mm (D) for easy mounting in busy systems

Applications


• Domestic appliances
• Automotive workshops
• Industrial robotics systems
