Frequently Asked Questions - RPS-300-24-C Mean Well

What is the output power and voltage of the Mean Well RPS-300-24-C?

The RPS-300-24-C provides a maximum output power of 300W at 24V DC, delivering up to 12.5A.

What safety certifications does this power supply have?

It is designed to meet medical safety standards such as UL/EN/IEC 60601-1. However, the unit is a component power supply; final product certification must be performed by the integrator.

Can I use this power supply for medical devices?

Yes, it is intended for medical applications. However, ensure that your final system complies with all applicable medical equipment standards.

What wire gauge should I use for the input and output?

Refer to the manual's wire recommendation table. For example, at 10A output, AWG 16 is suggested. Always ensure all strands are securely terminated.

How should I install the RPS-300-24-C?

Follow the PCB type installation instructions: ensure proper insulation distance (5mm bottom, 15mm around), avoid high moisture, and provide adequate cooling. For units >120W, forced air may be needed.

What are the cooling requirements?

The RPS-300-24-C relies on free air convection. However, since it exceeds 120W, forced air cooling is likely required. Check the specification sheets for minimum airflow intensity and direction.

Can I mount this power supply in any orientation?

Standard orientation is recommended. Other orientations may increase internal component temperature and require output current derating. Consult the derating curve in the specification.

Is EMC compliance guaranteed for end products?

The power supply is designed for component-level EMC compliance. When integrated into a system, the EMC characteristics of the final product must be re-verified.

What is the input voltage range?

It accepts a universal AC input from 90VAC to 264VAC.

Where can I find more detailed specifications?

Visit the official Mean Well website at www.meanwell.com and search for the RPS-300 series for datasheets, mechanical drawings, and application notes.

(1) Enclosed Type

(a) Before any installation or maintenance work, please disconnect your system from the utility. Ensure that it cannot be re-connected inadvertently!
(b) Mounting orientations other than standard orientation or operate under high ambient temperature may increase the internal component temperature and will require a de-rating in output current. Please refer to the specification sheets to receive the optimum mounting position and information about the de-rating curve.
(c) Fans or ventilation holes must be kept free from any obstructions. Also a 10-15 cm clearance must be kept when the adjacent device is a heat source.
(d) Keep enough insulation distance between mounting screws and internal components of Enclosed units. Please refer to case drawing on specifications to receive the maximum length of mounting screw.
(e) Recommended wires of Enclosed units are shown as below.

AWG	18	16	14	12	10
