RECOM Switching Regulator, 0.3AMaximum Input Current, ±1.5% Line Regulation - R-78HE-0.3 Series - R-78HE5.0-0.3

This switching regulator from RECOM adjusts your supply voltage to meet your equipment's needs. With its versatile input voltage range of 6.5 to 72V DC, it makes many standard energy sources compatible with your low-voltage devices for convenient power distribution. The unit's precise ±1.5% line regulation keeps its 5V DC output voltage stable, giving you a reliable energy supply for efficient working. To reduce appliance downtime, the converter comes with integrated short-circuit and overcurrent protection and automatically resets after tripping.

Features & Benefits

• Surge voltage rating of 100V prevents damage to your devices from electrical faults
• Compact dimensions of 11.5 (W) x 12.5 (H) x 8.5mm (D) fits into busy board-mounted systems
• Up to 83% efficiency for minimal heat build-up during operation
• Operating temperature range between -40°C and +105°C to perform in demanding settings

Applications

• Power tools
• Portable spotlights
• PA systems
• Manufacturing industry

How much current does this switching regulator use when not in operation?

The converter uses just 1.5 to 3mA of quiescent current to support your application's energy efficiency.
