The compact, high-efficiency ac-dc converters are certified to multiple standards and are high-density modules suitable for industrial applications, smart home and domestic appliances, telecommunications, street lighting and security systems.

The LMF500-20Bxx series of 500W ac-dc converters have built-in active Power Factor Correction (PFC). Models have a universal input of 80 – 264V ac and dual use of the same terminal enables it to also accept 110 – 370V dc. Output is 12 -54V.

The cost-effective, low no load power consumption ac-dc switching power supplies are reliable, with double or reinforced insulation. 

The ac-dc converters measure 203.1 x 101.6 x 40.6mm and have an operating temperature range of -30℃ to +70℃.

Other features of the LMF500-Series are high I/O isolation test voltage, up to 4,000V ac. Safety approvals include CE EN/ UL62368-1 for AV ICT (audio-visual, and information communication technology) equipment, IEC/EN60601 for medical equipment, EN60335 (the Low Voltage Directive) for household and electrical appliances, GB4943 and EN61558. The modules have output short circuit constant current, over-current, over-voltage class III (designed to meet EN61558) and over-temperature protection. There is also remote sense compensation and remote ON/OFF function.

Additionally, the ac-dc converters offer excellent EMC performance meeting CISPR32/EN55032 class B for both conducted and radiated emissions and EN61000-3-2 class A & D for harmonic currents.
