MORNSUN LMF500-20Bxx: 500W Medical & Industrial PFC Power Supply

When your application demands high power, strict safety certifications, and flawless performance—from medical devices to industrial automation—standard power supplies fall short. The MORNSUN LMF500-20Bxx Series is engineered to exceed these rigorous requirements. This 500W enclosed AC/DC switching power supply combines universal input, active Power Factor Correction (PFC), medical-grade safety approvals, and advanced control functions in a high-density metal enclosure, delivering a premium power solution for the world's most critical systems.

Core Features: Medical-Grade Safety with Industrial Muscle

The MORNSUN LMF500-20Bxx is not just another high-power supply. It is designed from the ground up to meet the stringent demands of both medical and industrial applications, featuring reinforced isolation and comprehensive protection.

  • Universal Input & Active PFC: It accepts a wide 80-264VAC input and simultaneously supports 110-370VDC on the same terminals. With active PFC, it achieves a power factor of 0.98 (115VAC) and 0.95 (230VAC) , ensuring grid-friendly operation and compliance with IEC/EN61000-3-2 Class A harmonic standards.
  • Medical & Industrial Safety Certification: Uniquely positioned, this series carries approvals referencing IEC/EN60601-1 for medical equipment, alongside IEC/UL62368-1EN60335, and EN61558 for industrial applications. It provides double or reinforced insulation with a 4000VAC I/O isolation test voltage, critical for patient contact and high-reliability systems.
  • Ultra-High Efficiency & Low Power Loss: Achieving typical efficiency up to 93% , it minimizes energy waste and thermal stress. Its low standby power consumption contributes to long-term energy savings in always-on installations.
  • Advanced Control & Protection: Unlike basic supplies, it features remote sense compensation (up to 300mV) to correct voltage drops over long cables and a remote ON/OFF function for system-level power management. Comprehensive protections include output short circuit constant current, over-current, over-voltage, and over-temperature protection with self-recovery.
  • Robust Environmental Performance: It operates reliably from -30°C to +70°C and delivers exceptional EMC performance with CISPR32/EN55032 Class B for both conducted and radiated emissions—a significant achievement for a 500W unit.
  • High-Density Enclosure: Housed in a rugged metal case measuring 203.10 x 101.60 x 40.60mm with forced air cooling, it provides 500W of clean power in a compact footprint.

Complete Product Model Selection

The series offers eight high-current models to meet the most demanding voltage requirements. All models feature active PFC, remote sense, and remote ON/OFF functionality (standard on 12V-54V models).
