RECOM DC-DC Switching Regulator, 0.65 W Rated Output Power, 800kHz Switching Frequency - R-78HB Series - R-78HB5.0-0.5/W

Rev up your low-powered systems with this switching regulator from RECOM. It's a versatile option that accepts a broad input voltage range from 9 to 72V DC and then smooths it out to the steady and reliable 5V DC output your equipment calls for. A high-efficiency rating of 86% means this device doesn't waste energy as heat while it works. As it stays cool as a cucumber, you can forget about installing a heatsink.

Features & Benefits

• Built-in protection diode supports high capacitive loads of up to 6800μF to suit demanding industrial applications
• Short-circuit protection nips unwanted surges in the bud to protect your equipment
• Small dimensions of 9.7 (W) x 12.1 (L) x 24mm (H) for space-saving installation on a PCB

Applications

• Battery-powered devices
• Manufacturing machinery
• Aerospace industry
• Cooling systems

How durable is this regulator?

This highly efficient regulator has a mean time between failures of 7,395,000 hours, so you can be sure it'll run like a well-oiled machine for years to come.

What type of battery can I use this product with?

This device lets you get the full potential out of 12, 24 and 36V batteries.
