MEAN WELL RS-35-5 30W 5V 6A Enclosed Switching Power Supply, 85-264VAC Input, Metal Case

Industrial control panels, LED lighting rigs, and automation systems often need a compact, reliable DC source that won’t quit. The MEAN WELL RS-35-5 delivers a steady 5V at up to 6A from any mains voltage between 85 and 264VAC, making it a go-to for engineers and technicians who build or service equipment across different power grids.

Why choose it

The RS-35-5 is built for longevity and stability. Its enclosed metal case shields against electromagnetic interference and physical contact, while the wide input range means one unit can be deployed in installations worldwide. Overload and short-circuit protection prevent damage to both the supply and the load, reducing downtime and maintenance costs.

Ideal use cases

• Powering sensors, relays, and controllers in industrial automation
• Driving 5V LED strips or indicator lights
• Bench testing and prototyping of 5V circuits
• Replacement supply for legacy equipment with 5V rails
• Telecom and networking devices requiring isolated DC

Good to know

The RS-35-5 uses convection cooling, so no fan is needed—silent operation and fewer moving parts. Adjust the output voltage slightly via the built-in potentiometer to compensate for cable drops. Mount it on a metal chassis for best heat dissipation, and keep ambient temperature within the rated range for full 30W output. Derating may apply above 50°C.
