The MVFC series has the advantages of universal input voltage range, AC/DC dual-use, low power consumption, low ripple and noise, high reliability, and safe isolation. It can be soldered on various types of PCB boards of electronic instruments or industrial automation equipment. The use of flame-retardant plastic case and potted with silicone facilitates the heat dissipation. It can provide the basic dustproof and waterproof functions, and can also meet the vibration-proof requirements of 5G. The EMC and safety specifications can meet the IEC/EN61000-4, CISPR32/EN55032, IEC/EN/UL62368, IEC/EN60335, and EN62477 certification standards.
