Product information

Description

The MEAN WELL RD-125B is a reliable 125 W dual output power supply and voltage converter designed for industrial and electronic applications. It operates with an input voltage range of 176 to 264 V and delivers a 5 V output alongside a 24 V output. Built with RoHS compliance and high energy efficiency, this power adapter ensures stable performance for various electronic devices and systems. Ideal for professional installations requiring steady power conversion.

Advantages

This dual output power supply provides stable and continuous power conversion for demanding industrial and electronic setups. Operating with free air convection, it maintains efficient thermal management without relying on noisy cooling fans, which helps improve overall reliability and longevity. The unit supports dual outputs at 5Vdc and 24Vdc, making it versatile for systems that require different voltage levels simultaneously. Built to meet stringent industry standards, it ensures safe and consistent performance under regular operating conditions.

Suitable for

  • Industrial automation and control systems
  • Electronic equipment requiring dual voltage rails
  • Professional electrical installations
  • Projects utilizing 5Vdc and 24Vdc components

When it may not be suitable

This power supply is not intended for consumer electronics that require portable or plug-and-play external adapters. It is also unsuitable for applications operating outside the specified input voltage range of 176 to 264 V or environments requiring active forced-air cooling systems.

Key specifications

  • Power rating: 125 W
  • Input voltage: 176 - 264 V
  • Output 1: 5 V DC at 10 A
  • Output 2: 24 V DC at 5 A
  • Cooling type: Free air convection
  • Design: Enclosed AC-DC dual output power supply

How to use

Mount the power supply securely within a suitable enclosure or professional rack that allows adequate space for free air convection. Ensure the mains input voltage matches the specified range of 176 to 264 V before connecting the wiring. Connect the AC input terminals to the correct line, neutral, and ground points following standard electrical safety guidelines. Attach your electronic loads to the appropriate 5Vdc and 24Vdc output terminals, ensuring polarity and current limits are respected. Verify all connections before powering on the system.

What to consider before purchase

  • Verify that your input voltage matches the 176-264 V range
  • Check if the dual output voltages of 5V and 24V match your device requirements
  • Ensure proper enclosure and ventilation for free air convection cooling
  • Confirm total power consumption does not exceed the 125 W limit

Usage recommendations

Always disconnect the mains power before performing any installation, wiring, or maintenance work. Ensure that the mounting location provides sufficient airflow for free air convection to prevent overheating during continuous operation.
