RECOM Switching Regulator, 4g Weight, 0.2% Load Regulation - R-78B-1.0 Series - R-78B3.3-1.0

Want to take control of power outputs? Trust this switching regulator from RECOM to GET the levels right. It steps 32V DC inputs down to 3.3V DC outputs, so it's Ideal for applications that have low energy demands. Its epoxy housing is non-conductive to keep you safe from shocks, while the plastic casing stops burning in less than 10 seconds, so you're also protected in the event of a fire. Through-hole mounting means you can achieve an unshakeable connection in a jiffy.

Features & Benefits

• 89% efficiency means minimal power is lost as heat, to keep your system running cool

• Compact dimensions of 11.5 (L) x 17.5 (D) x 8.5mm (W) mean it's space-efficient

• 0.4% line and 0.2% load regulation give consistent power for reliable performance

• Light 4g weight puts little strain on your system

• Mean time between failures of 6,584,000 hours means you can rely on it to go the distance

Applications

• Telecommunications industry

• Robotics system

• Distribution centres

• Sensing operations

Can I use this device in factory settings?

Yes. This unit has a broad operating temperature range between -40°C and +85°C, so it's suitable for use in harsh industrial environments.
