The Guardian series of DC power systems are 48V solutions that are available in shelf, rack, and cabinet configurations. Power densities exceeding 27W/", or 25kW per one rack unit, maximise the system space dedicated to revenue-generating equipment and/or batteries in fixed and mobile network applications. All systems provide industry-leading reliability and the capability to operate in environments with poor power-grid quality. Rectifiers feature a wide-range 90 to 300VAC 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 significantly reduces rectifier component stresses. The Guardian DC solutions can be readily tailored to power an expansive array of applications. Power shelves are available from 150 to 500A in 2RU to 6RU heights. Rack and cabinet systems can deliver up to 500A.
