Power-One's Aspiro 48V XR08.48 front-end rectifier, providing 800W, uses digitally controlled rectifiers that can adapt, without derating, to a wide range of line, load and temperature conditions. This adaptive capability is designed to significantly reduce logistics costs for service providers by enabling a one-solution deployment to power a wide range of wireline, wireless and triple-play applications in cellular and WiMAX base stations and in the enterprise.

"Only the Aspiro Power System offers competitive power densities without performance deratings from -40C to 65C and across an AC input range of 84-300V," said Bill Yeates, Power-One CEO. "In addition, our digitized control and resonant-switching techniques have reduced component count by 40 percent, increasing reliability and further reducing total cost of ownership for communications service providers."

The product has a 300mm deep ETSI form factor with 1- and 2RU height options, NEBS level-3 compliance, Class B EMC and hardwired ETSI or IEC 320 AC connectors, the company said. Distribution options include up to 12 circuit breakers, configurable by distribution and battery, or 10 GMT fuses and optional low voltage disconnects.

In addition, four XR08.48 systems, with 90 percent efficiency, can deliver 3200W from a 1U shelf. A 400W XR04.48 rectifier is also available with the same 4-by-1.6-by-9-inch form factor as the 800W product to reduce initial costs for lower-power systems and simplify migration paths when more power is needed.

Pricing and other information can be obtained directly from the company.
