These low profile, encapsulated print-mountable modules in an industry-standard pinout deliver full output power from -40C to +80C and are certified for operation up to +90C air Single Output 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.
