ANDOVER, Mass., 30 March 2011. Vicor Corp. in Andover, Mass., is introducing the IBC050 series VI BRICK bus converterpower electronics products with 36-to-60-volt input ranges to 650 Watts for telecommunications, computing, data storage, networking, and Power-over-Ethernet applications. The eighth- and quarter-brick IBC050 series expands on the 38-volt to 55-volt input range of Vicor's IBC048 modules.The bus converters are available as drop-in upgrades for industry-standard 5:1 and 4:1 converters, and can be 98 percent efficient. The input range provides 2,250 volts DC isolation from input to output, and complies with ETSI EN300 132-2 for 48-volt telecommunications applications requiring 5:1 or 4:1 bus conversion from input voltages as low as 36 volts and as high as 60 volts, Vicor officials say.The input-to-output isolation complies with IEEE 802.3 Power-over-Ethernet (PoE) standards. The Vicor (NASDAQ: VICR) IBC050 modules support output bus voltages of 7 to 12 volts (5:1) or 8.7 to 15 volts (4:1) over the line and load range.

IBC050 series modules use Vicor's Sine Amplitude Converter topology, and are pin-compatible with industry standard square-wave bus converters. The VI BRICK bus converter use the same Vicor patented ZCS/ZVS resonant converter technology that powers V.I Chips in high-performance factorized power architecture applications.

Switching at about 10 times the frequency of square-wave converters, IBC050 modules cut transient response time by a factor of 10, eliminating the need for external bulk capacitors, Vicor officials say. For more information contact Vicor online at www.vicorpower.com.
