Guardian Access 19 are 5RU or 6RU high 19” rack-mounted, integrated DC power systems providing an output of -48VDC. These systems can accommodate up to four (5U) or eight (6U) Guardian family high efficiency hot-swap rectifiers.
A load current of 400A is available with battery charge current up to 125A subject to an overall 480A. The rectifiers are internally fan cooled with speed control which is a function of load and temperature, keeping acoustic noise to a minimum.
The DC output circuits can provide up to 20 loads which utilize circuit breakers with capacities from 2A to 150A plus up to six 100A or 300A breakers that provide battery protection. A programmable low voltage battery disconnect (LVBD) is available with a 200A (5RU systems) or 400A (6RU systems) contactor; while one optional partial load disconnects (PLD), rated at 125A (5RU systems) or 200A (6RU systems) and also programmable, can provide non-critical load shedding when operating on batteries.
