The LOF450 and LOF550 medically-approved, open frame AC/DC converters have been added to Mornsun’s LOF series of medical and industry standard power supplies. They are available from Relec Electronics in industry standard packages and on short lead times.  

Both have the same thermal performance as existing members of the series. The low cost, reliable AC/DC converters meet the latest regulatory standards.

The LOF450 series has a universal AC input (90 to 264V AC) and accepts an input of 127 to 373V DC input, with output ranging from 12 to 48V.

The 450W AC/DC converters operate at -40°C to 70°C and measure just 127 x 76.2 x 38.5mm (5.0 x 3.0 x 1.5 inch), making them suitable for use in confined spaces.

Models in the 550W LOF550 series have the same universal input and output ranges and temperature range but are slightly higher, with dimensions are 127 x 76.2 x 38.5mm (5.0 x 3.0 x 1.6 inch).

Both new AC/DC converters have double or reinforced insulation with EMC and safety performance. In addition to meeting IEC/EN/UL62368, GB4943, IEC/EN60335, IEC/EN61558, IEC/EN/ES60601, they are EN60601 2xMOPP and UL/EN62368-1-approved.

Target applications are industrial, LED, street lighting control, electricity, security, telecommunications, smart buildings and homes and medical environments.

The open frame models in both series are also available as perforated case (-C) or perforated case with integrated fan (-CF) models.
