Information about the MEAN WELL RPS-300-12

The MEAN WELL RPS-300-12 is a highly reliable medical-grade open-frame power supply specifically engineered for high-density 5" x 3" applications where space is at a premium. This unit is fully compliant with 2 x MOPP (Means of Patient Protection) safety standards and is BF (Body Floating) rated, making it an ideal energy source for medical equipment with direct patient contact. Its "green" power characteristics include an exceptionally low leakage current of less than 150 µA and a standby power consumption of under 0.5W, ensuring both superior safety for clinical environments and high energy efficiency for modern diagnostic tools.

Technically, the RPS-300-12 offers a robust 12V DC output with the ability to deliver a full 300W under forced air cooling or 200W through natural convection. Unique characteristics of this model include its comprehensive signal set, featuring Power Good (P.G.) and Power Fail (P.F.) indicators, along with a built-in 12V fan supply and 5V standby output to simplify system integration. With a 90% efficiency rating and a typical lifetime exceeding 40,000 hours, this power supply provides the industrial-grade durability required for hemodialysis machines, medical monitors, and sleep apnea devices, all supported by a 3-year manufacturer warranty.
