Power Supply Customization
The modular front ends may be specified for operation from 48Vdc or 115/230Vac and incorporate Vicor's FIAM or FARM modules to provide transient protection, EMI filtering, autoranging and bridge rectification. 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 in industry standard full, half, and quarter brick packages provide up to three independently regulated outputs of 1.8 to 48V at power levels up to 900 Watts. An output trimming range of 10% to 110% down to as low as 500mV provides additional flexibility. Other special features include output sequencing, overvoltage protection on all outputs, and no minimum load requirement. Power densities up to 23 W/in are available.
For AC input systems, the partitioned architecture of VIPAC permits locating hold-up capacitors remotely, providing a variety of packaging and placement options. Reliability is enhanced by thermally decoupling the capacitors from the converters and chassis.
Availability of multiple mechanical platforms with profiles as low as 0.75 simplifies the integration of a VIPAC power supply in a variety of systems. Application specific thermal interfaces allow the user to specify cold plate, 0.5 or 1 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 as high as 65 ° C.
Using the Web-based power supply selection tool named VCAD, users will be able to configure their power supplies online.
