Shelf, Rack and Cabinet DC Power Systems
Power-One, Inc. announces its Guardian series of DC power systems that are available in shelf, rack and cabinet configurations. Power densities exceeding 27W per cubic inch or 25 kW per one rack unit maximize the system space dedicated to revenue-generating equipment and/or batteries in fixed and mobile network applications. All systems provide the capability to operate in environments with poor power-grid quality. Rectifiers feature a range of 90 to 300 VAC input with high input voltage shutdown and the ability to withstand a loss of phase or neutral without damage. Reliability is increased through the use of an advanced resonant soft-switching topology which reduces rectifier component stresses. The systems can be tailored to power an array of applications.
