RECOM DC-DC Converter, 91 to 93% Efficiency, Remote On-Off Control - R-5 Series - R-543.3PA

Is finding an efficient switching regulator your TOP priority? Look to this DC-DC converter from RECOM. It accepts inputs anywhere between 4.5 and 18V DC and steps them down to an adjustable 3.3V DC with an accuracy of ±1%. This makes it practical for running your sensitive DC-powered components. A 91 to 93% efficiency rating means minimal energy is wasted as heat and you won't need a heatsink to keep things cool. You can Trust this is a reliable choice thanks to its comprehensive electrical safety mechanisms, including overload and short-circuit protections with automatic recovery. There's even remote ON/OFF control so you can manage your device from a distance.

Features & Benefits

• Typical load regulation of 1% means you GET tightly controlled output values

• Autosense function compensates for losses caused by long circuit loops

• Flame-retardant package materials help ensure safety in case of fire

• Mean time between failures of 749,000 hours, so it's a long-lasting choice

Applications

• Renewable energy circuits

• Smart lighting

• Medical devices

What temperatures can I use this converter in?
