Bus converter power electronics modules with 36-to-60-volt input ranges to 650 Watts introduced by Vicor

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.
