These modules deliver full load output power from -40C to 75C across Single the entire input range of 80VAC to 305VAC and are certified for operation with power derating up to 90C air ambient. A peak load capability of up to 150% supports dynamic power demands of applications. This series of Output 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 (5.75kV DC) isolation, these are the easiest to use modular power solutions in the industry.
