RECOM Switching Regulator, 12V DC Output Voltage, 15 to 32V DC Input Voltage - R-78B-2.0 Series - R-78B12-2.0

Use this switching regulator from RECOM to covert your supply voltage to the level needed by your equipment. It provides a continuous 12V DC output, giving you a reliable power supply that helps avoid unplanned appliance downtime. The product's wide input voltage range between 15 and 32V DC means you can use it with common electrical sources. As it efficiently converts up to 96% of its input energy, very little heat is produced as a by-product. This means you can be confident it works safely without the need for an external heatsink.

Features & Benefits

• Quiescent current of 2mA means minimal energy waste while not in use

• Peak ripple voltage of 75mV means low disruption from electrical noise

• Body measurements of 11.5 (W) x 17.5 (H) x 8.5mm (D) mean it fits easily onto busy circuit boards

• Short-circuit protection resets the device after faults to help minimise downtime

Applications

• Games consoles

• Radio receivers

• Security systems

• Logistics industry

How do I mount this switching regulator?

This switching regulator is suitable for the through-hole mounting method, which achieves a secure and vibration-proof attachment.
