AC/DC Converter
RAC02E-K/277
Description
The cost-efficient RAC02E-K/277 AC/DC converter series has an input range of nominal 100VAC to an
enhanced 277VAC, delivering an uncompromising 2 watts of output power with tightly regulated outputs
from 3.3V to 24VDC. These low profile, encapsulated print-mountable modules in an industry-standard
pinout deliver full output power from -40°C to +80°C and are certified for operation up to +90°C air
ambient with output power reduced to 1.2W. This series of AC/DC modules holds international safety
certifications for industrial, domestic, ITE, use with 4kVAC input to output isolation, they are suitable for
worldwide applications in automation control, industry 4.0, IoT. 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.
