RAC03E-K/277 AC/DC converter series has an input range of nominal 100VAC to an enhanced 277VAC, delivering an uncompromising 3 watts of output power with tightly regulated output. These low profile, encapsulated print-mountable modules in an industry-standard pinout deliver full output power from -40°C to +75°C and are certified for operation up to +85°C air ambient with output power reduced to 1.8W. This series of AC/DC modules holds international safety certifications for industrial, domestic, ITE and household use. With 4kVAC input to output isolation, they are suitable for worldwide applications in automation control, industry 4.0, IoT and household automation. Due to their LPS (Limited Power Source) and reinforced class II installation rating for floating outputs and their significantly wide margin to class B EMC compliance without external components, these are the easiest to use, versatile power modules in the industry.
