Vicor Intros VIPAC Family of Power Solutions
Vicor (Andover, MA) announced the introduction of the VIPAC family of power solutions, which the company claims offers configuration flexibility, high power density and fast time to market. The VIPAC family's modular construction combines pre-assembled and tested front-ends with one or more of Vicor's second generation dc/dc converters on a choice of platforms.
The modular front ends may be specified for operation from 48Vdc or 115/230Vac and incorporate Vicor's FIAM or FARM modules. A microprocessor-controlled interface provides programmable output sequencing, serial number readback, bus OK, bus voltage monitoring, master enable and real-time control of power-up and power-down sequencing.
The dc/dc converters come in full-, half- and quarter-brick packages and provide up to three independently-regulated outputs of 1.8V to 48V at power levels up to 900W. They feature an output-trimming range from 10 percent to 110 percent, down to as low as 500mV. Other features include output sequencing, over-voltage protection and no minimum load requirement. Power densities up to 23W/cubic inch are available.
For ac-input systems, VIPAC's partitioned architecture permits locating hold-up capacitors remotely. Multiple mechanical platforms are available with profiles as low as 0.75". Application-specific thermal interfaces are designed to allow the user to specify cold plate, 0.5" or 1.0" heat sinks to best suit the environmental requirements and thermal management system.
VIPAC is designed for use in conduction, convection or forced convection environments with ambient temperatures no higher than 65 degrees C. Prices start as low as $0.55/W in 500-piece quantities. Selected units are available beginning in mid-March 2001.
