Vicor VIA PFM AC-DC front-end module

Vicor Corporation has introduced its high-density, low-profile, integrated VIA PFM AC-DC front-end power modules. The converter modules achieve a power density of 8 W/cm³ supplying an isolated, PFC-regulated 24 or 48 V SELV DC output at up to 400 W from the universal AC input range of 85 to 264 V with 93% peak efficiency.

The product is said to be 5x thinner than traditional 1U supplies, offering advantages to power system architects challenged by size constraints. With its 9 mm thin profile and 36 mm width, the device can be mounted on the sidewall of any typical 1U chassis.

The thermally adept units may be chassis mounted and conduction cooled to eliminate fans, thereby improving overall system reliability and minimising the power system footprint. High density, high efficiency and low thermal resistance make the modules suitable for a wide range of applications, including small-cell wireless base stations, size-constrained LED lighting applications and industrial and automation systems.

The power modules enable power system designers to create dense, efficient, flexible and scalable power systems. They integrate system functions including EMI filtering, transient protection and inrush current limiting to reduce design time and design risk. Available in chassis-mount and PCB-mount configurations, the modules support a multiplicity of mechanical mounting and thermal management options.
