## Summary description

Mean Well RS-75-12 is a 72 W switch-mode power supply for servers and industrial equipment. Outputs 12 V DC, accepts AC input 88–264 V and 47–63 Hz, with passive cooling and metallic enclosure. Compact dimensions (97 × 129 × 38 mm) and 1200 ms rise time make it suitable for rack-mounted or embedded systems requiring reliable low-noise DC power.

## Long description

Mean Well RS-75-12 is a 72 W switch-mode power supply designed for servers, industrial equipment and embedded systems that require a compact, reliable low-noise 12 V DC source. The unit accepts a universal AC input of 88–264 V at 47–63 Hz, uses passive cooling via a metallic enclosure and provides built-in protections against short circuit, overload and over-voltage. Compact dimensions (97 × 129 × 38 mm), an LED power-on indicator and low no-load consumption make this power supply suitable for rack-mounted or space-constrained applications where stable DC power and high efficiency are required.
Advantages
The RS-75-12 combines a full-range AC input with high efficiency and low standby consumption, delivering 12 V DC with minimal audible noise thanks to convection cooling. It includes protective functions for short circuit, overload and over-voltage to safeguard connected equipment. The metallic enclosure and components qualified by full-load burn-in and long-life electrolytic capacitors improve reliability and thermal stability up to 70°C operating temperature. The unit also survives surge input conditions and vibration tests, supporting robust industrial use.
Suitable for
 Server power rails and control modules
 Industrial automation controllers and PLCs
 Embedded systems and rack-mounted electronics
 Telecommunications equipment and network devices
 Test benches and laboratory instrumentation

How to use
Install the RS-75-12 in a location with adequate ventilation for convection cooling and secure it according to the mounting recommendations for your rack or enclosure. Connect the AC mains within the specified 88–264 V range and verify polarity and wiring for DC outputs before powering connected devices. Observe the LED indicator to confirm power-on and monitor the load to ensure it does not exceed the rated 72 W. Ensure wiring and connectors are rated for the output current and that the system grounding meets safety requirements.
Usage recommendations
For long-term reliability, operate the power supply within the specified temperature range and avoid obstructing airflow around the metallic enclosure. Use appropriate fusing on the AC input and implement additional downstream protection if the connected equipment requires stricter fault isolation. Periodic visual inspections of electrolytic capacitors and terminal connections are recommended in demanding industrial environments.
