The MVAC400 is a 400W, open frame, medically compliant, AC/DC power supply in an industry-standard 3in by 5in footprint and 1U-compatible height profile. Models are available with 12V, 24V, 48V, or 54V main output. The MVAC400’s high convection rating of 250W makes it suitable for industrial applications where fans are often undesirable due to audible noise and reliability concerns. Two fully regulated and isolated auxiliary outputs are standard on the MVAC400 series: a 5V/10W standby output that is active when the main output is inhibited, and a 12V/12W fan output. With efficiencies up to 94%, these low wattage supplies afford users simplified thermal management by evolving less heat than competitive offerings. With remote sense, power OK, and PS-ON control and signal lines these supplies are fully featured to support most applications. Current sharing is an available option for parallel-redundant configurations with droop current share with the AFR models, with internal ORing with the AFT models and with an external ORing FET with the AFD models.
