MEAN WELL RPS-400-24-SF 400.8W 24V 16.7A Medical Power Supply with PFC and Fan

Medical devices demand power supplies that are not only reliable but also meet stringent safety standards. The MEAN WELL RPS-400-24-SF delivers 400.8W of clean 24V DC power with 2xMOPP medical isolation, making it ideal for patient-contact equipment where leakage current must be minimal. Its compact 5"x3" enclosed design with built-in fan ensures dependable operation even in tight spaces.

Who is it for

This power supply is built for medical equipment manufacturers, laboratory technicians, and system integrators who need a certified, high-efficiency power source for devices such as patient monitors, diagnostic instruments, surgical tools, and portable medical carts. It is equally suited for industrial applications requiring a robust, fan-cooled power supply with active PFC.

Main features

• High efficiency up to 94% reduces energy waste and heat generation, lowering cooling costs.
• 2xMOPP medical safety approval (ANSI/AAMI ES60601-1, TUV EN60601-1) with <150 µA leakage current for patient safety.
• Built-in active PFC (Power Factor Correction) ensures compliance with harmonic current standards and improves power quality.
• Wide input voltage range of 80~264 VAC (113~370 VDC) allows operation from unstable mains or DC sources worldwide.
• Comprehensive protection: short circuit, overload, over voltage, and over temperature safeguards both the supply and connected equipment.
• Forced air cooling via built-in DC fan maintains performance in ambient temperatures from -30°C to +70°C.
• Compact 5"x3" enclosed form factor saves space in medical carts, panels, and equipment enclosures.
• Low no-load power consumption (<0.5 W) meets energy efficiency regulations when the device is idle.
• High MTBF of 300,000 hours (MIL-HDBK-217F) indicates long-term reliability in critical applications.
• Safety approvals: CB, CE, EAC, UKCA, UL, cUL, TUV for global market access.

Tips

Ensure adequate airflow around the unit when installing in an enclosure; the built-in fan requires unobstructed vents. For medical applications, verify that the leakage current and isolation meet your specific patient protection requirements. Use appropriate wire gauges for the 16.7A output to minimize voltage drop. Consider derating the output power at ambient temperatures above 50°C or at altitudes above 2000 meters, as per the datasheet.
