RECOM Switching Power Supply, Encapsulated Type, 820μF Capacitive Load Maximum - RAC04-C/277 Series - RAC04-15SC/277-E

Good things come in small packages – look to this switching power supply from RECOM if you want proof. It has dimensions of 36.7 (L) x 27.2 (W) x 17.1mm (H), so calls for minimal board space. Give it voltages of 80 to 305V AC and you'll get a 15V DC output in return. This is ideal for personal computers or handheld electronics. To put your mind at ease and boost workplace safety, this power supply features short-circuit protection to prevent damage to your setup if a surge occurs.

• Wide operating temperature range between -40°C and +80°C to suit demanding applications
• Silicone potting is non-conductive to prevent electricity or noise from escaping the casing
• Comes in a tube of 12 units for convenience

Applications

• Computer production
• Manufacturing equipment
• Telecommunication networks
• Security systems

Why should I use a switching power supply over a linear regulator?

Encapsulated switching power supplies like this one are excellent all-rounders that aren't just energy-efficient but also heat-efficient. This means they cost less to run and power devices more effectively than linear regulators.
