Relec presents Mornsun’s LMF500-20Bxx series AC-DC converters

The LMF500-20Bxx series now available from Relec Electronics are compact, high-efficiency AC-DC converters certified to multiple standards. These high-density modules are said to be 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 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.
