LFM550M Series

APPLICATION

The LFM550M Series 550 Watt Medical AC-DC Power Supply with PFC is engineered for high-efficiency performance and medical-grade safety. With a universal input range of 85–264 Vac and efficiencies up to 94%, it supports Class I and Class II applications in a compact 25.4 mm profile.

Output options range from 12 V to 54 V with up to 45.83 A available, and models support both fan and conduction-cooled designs. Built-in protections include overvoltage, overtemperature, and continuous short circuit protection. Voltage regulation is tight with up to ±0.3% line and ±0.5% load accuracy, and ripple is minimised across all models.

Certified to IEC/EN/UL 60601-1 (2 x MOPP), IEC/EN/UL 62368-1, and EN 60335-1 standards, the LFM550M series meets stringent EMC and immunity requirements, making it ideal for medical devices, patient monitoring systems, and other healthcare equipment operating in demanding environments.
