Information about the MEAN WELL RPS-300-48

The MEAN WELL RPS-300-48 is a high-voltage 48V medical-grade open-frame power supply designed for sophisticated healthcare applications requiring maximum efficiency in a compact 5" x 3" footprint. This PCB-type unit is engineered to meet the stringent 2 x MOPP safety standards and is BF (Body Floating) rated, ensuring it is safe for medical devices with direct patient contact. Its "green" power characteristics are a major strength, featuring an extremely low leakage current of less than 150 µA and a no-load power consumption of under 0.5W, providing a highly secure and energy-efficient solution for medical monitors, diagnostic systems, and precision healthcare electronics.

Technically, the RPS-300-48 stands out with an impressive peak efficiency of 92.5%, significantly reducing heat dissipation within medical enclosures. It delivers a robust 300W output with forced air cooling and maintains 200W under natural convection. Unique characteristics include its integrated 12V fan supply, a dedicated 5V standby output, and Remote Sense technology which ensures consistent 48V delivery by compensating for wiring voltage drops. With its 3-year manufacturer warranty and a typical lifetime exceeding 40,000 hours, this power supply provides the industrial-grade stability necessary for mission-critical medical pumps, imaging equipment, and electric hospital beds.
