RECOM Switching Regulator, 1A Maximum Input Current, 91% Maximum Efficiency - R-78E-1.0 Series - R-78E5.0-1.0

Adapt your power source to suit your board-mounted hardware with this switching regulator from RECOM. It converts up to 91% of your input voltage into compatible power for your devices, minimising energy waste for high system efficiency. The converter outputs a current of 1A to provide a reliable electrical supply that's suitable for your system's basic functions. As it has compact body measurements of 11.6 (width) x 10.4 (height) x 8.5mm (depth), the component fits neatly into busy systems.

Features & Benefits

• Accepts input voltages between 8 and 28V DC for compatibility with common power supplies
• Draws a 1.5mA quiescent current when not in use for energy efficiency
• Simple through-hole mounting makes for easy installation
• Supports operating temperatures between -40°C and +85°C to work in tough industrial conditions

Applications

• Surveillance cameras
• Battery-powered devices
• Signalling systems
• Telecommunications

Do I need to protect this switching regulator against electrical faults?

No, you don't need to install extra fault protection for this switching regulator because it comes with built-in short-circuit and anti-overcurrent measures. To reduce downtime, the converter automatically resets after short-circuiting.
