Product Details

Mean Well RS-25-5 5V 25W Switching Power Supply

The Mean Well RS-25-5 power supply is a compact 5V 25W enclosed switching PSU designed for low-voltage electronics, control systems, equipment assemblies, and compatible 3D printer builds. It provides a regulated 5V DC output in a small chassis-mount format, making it a practical choice when a dedicated 5V supply is needed.


Compact 5V Power for Electronics and Equipment Builds

This RS-25-5 switching power supply is useful for applications that require a stable 5V DC source within the rated output limits. Common uses include control electronics, small machine assemblies, lighting or signal circuits, embedded projects, and compatible 3D printer electronics.

Although this product may be used in certain Voron-style or custom 3D printer builds, it should be positioned as a general-purpose 5V switching power supply rather than a printer-only part.


Mean Well RS-25-5 Power Supply Features

The Mean Well RS-25-5 includes universal AC input, free-air convection cooling, a power-on LED indicator, and built-in protection features for short circuit, overload, and over-voltage conditions. Its enclosed metal frame design makes it suitable for mounting inside compatible equipment enclosures or protected electrical compartments.


General-Purpose Applications

This 5V 25W PSU can be used in a wide range of compatible low-voltage DC applications where the voltage, current, wiring, ventilation, and installation environment are suitable. Always confirm the electrical requirements of your project before installation.


Common Uses

  • Low-voltage electronics projects
  • Control boards and small equipment assemblies
  • Compatible 3D printer electronics and custom printer builds
  • Dedicated 5V auxiliary power circuits
  • Machine control panels and enclosure-mounted electronics
  • Replacement PSU for compatible 5V systems

Verification note: Confirm the product photo matches the RS-25-5 model before publishing. Remove unrelated fabrication wording from the existing specifications tab, including “CNC Laser Cut & Hand-Assembled in Marathon, ON,” because it does not apply to this power supply.

Installation & Care

Installation

  • Confirm that the Mean Well RS-25-5 power supply matches the voltage, current, and wattage requirements of your project before installation.
  • AC mains wiring should only be completed by someone qualified and comfortable working with electrical systems.
  • Disconnect power before wiring, adjusting, mounting, or inspecting the power supply.
  • Verify input voltage, output voltage, polarity, grounding, and terminal connections before powering the unit.
  • Install inside a suitable enclosure or protected electrical compartment to reduce exposure to accidental contact, dust, debris, and damage.
  • Provide adequate airflow for free-air convection cooling.
  • Do not exceed the rated 25W output capacity.

Handling

  • Handle by the frame and avoid touching terminals when the unit is connected to power.
  • Keep metal chips, wire strands, dust, and conductive debris away from the power supply.
  • Inspect the unit before installation for shipping damage, loose terminals, or visible defects.

Care

  • Periodically inspect wiring, terminal tightness, mounting hardware, and ventilation areas.
  • Keep the power supply dry and protected from moisture unless installed within a properly rated enclosure.
  • Replace the unit if it shows signs of overheating, physical damage, unstable output, corrosion, or electrical failure.
  • Do not modify the power supply or use it outside the manufacturer’s rated specifications.
