All AC/DC converters in the LD-R2 Series meet EN55032 class B EMC standards without the need for external components and have a no load power consumption of less than 0.1W, making them perfectly suited for household and domestic applications. Other safety approvals include EN/UL62368 for audio, video and IT equipment and EN60335 and EN61558 for household, domestic appliances and power transformers. Operating temperature range is -40 to +85°C.

All models have compact dimensions, a universal input range of 85-305Vac and output range of 3.3-24Vdc.

The LD03 R2 Series of 3W AC/DC converters measure 25.4 x 25.4 x 17.6mm and are CB / CE / UL EN62368-approved. EMI performance meets CISPR32 / EN55032 CLASS B, EN55014. Efficiency is up to 79%.

The LD05 R2 Series 3W AC/DC converters measure 25.4 x 25.4 x 17.6mm and are CB / CE / UL EN62368-approved. EMI performance meets CISPR32 / EN55032 CLASS B, EN55014. Efficiency is up to 81.5%.

The 10W LD10 R2 Series AC/DC converters measures 40 x 25.5 x 21mm and are approved to EN / UL / CE EN62368 / 60335 / 61558. Efficiency is up to 85%.
