Vicor packs 400W AC/DC front-end module in 9-mm profile

May 19, 2015 // By Graham Prophet
Vicor's VIA PFM AC-DC front-end modules are power-factor-corrected, high-power-density isolated converters that provide up to 400W at 24 or 48V in a 9-mm profile, module that Vicor terms Thermally Adept.

VIA PFM AC-DC front-end converter modules achieve a power density of 8 W/cm³ (127 W/in³) supplying an isolated, PFC regulated 24V or 48V SELV DC output at up to 400W from the universal AC input range of 85 to 264V with 93% peak efficiency.

The VIA PFM is one-fifth the thickness of traditional 1U supplies, offering design advantages to power system architects challenged by size constraints. With its 9 mm thin profile and 36 mm width, the VIA PFM can be mounted on the sidewall of any typical 1U chassis, saving valuable real estate. Thermally adept VIA PFMs may be chassis mounted and conduction cooled to eliminate fans, thereby improving overall system reliability and further minimising the power system footprint. High density, high efficiency and low thermal resistance suit VIA PFM front-end modules to a wide range of end-market applications, including small cell wireless base stations, size constrained LED lighting applications, industrial and automation systems.

VIA power modules enable power system designers to create highly dense, efficient, flexible and scalable power systems. Vicor’s 9 mm profile VIA power modules 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, VIA power modules support a multiplicity of mechanical mounting and thermal management options.

Vicor’s online PowerBench design tool suite enables designers to model a complete AC to PoL power system with a modular power component design methodology. The PowerBench tool suite provides the ability to configure and visualise end-to-end power systems and dynamically analyse system performance, accelerating design cycles and reducing development costs.

VIA PFM front-end power modules are priced from $107 for OEM quantities.
