RAC04-K/277
Description
The RAC04-K/277 series delivers an uncompromising 4 watts of continuous output power (6W peak) in harsh
industrial and household environments. These modules deliver full load output power from -40°C to 75°C across
the entire input range of 80VAC to 305VAC and are certified for operation with power derating up to 90°C air
ambient. A peak load capability of up to 150% supports dynamic power demands of applications. This series of
fully encapsulated AC/DC modules is a complete solution without the need for external components which supports
Ecodesign Lot 6 standby mode operation for worldwide applications in automation, industry 4.0, IoT, household,
and home automation. With international safety and EMC certifications for industrial, domestic, ITE, and household
applications, these are some of the most versatile power modules on the market. Due to their reinforced class II
installation rating for floating outputs and their significantly wide margin to class B emissions compliance without
external components and a certified 4kV AC (5.25 kV DC) isolation, these are the easiest to use modular power
solutions in the industry.
