Guardian Hybrid M44H
Guardian Hybrid M44H
Available in EMEA / APAC Regions only
Product Information
Guardian M44 Hybrid is a 8RU or 10RU high 19” rack-mounted, integrated hybrid power system providing an output of 48VDC. These systems can accommodate between eight 8 or 12 Guardian family FMPe30.48J hot-swap rectifiers plus an equal number of FPV30.48G hot-swap solar converters.
Maximum load current is 700A with software controlled battery charge current, subject to a total 700A of load plus charge. The rectifiers / solar converters 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 23 loads which utilize circuit breakers with capacities from 4A to 150A plus up to six 100A to 300A breakers that provide battery protection. An optional programmable low voltage battery disconnect + shunt (LVBD) with 600A capacity is available for use with Lead Acid batteries; while an optional partial load disconnects (PLD), rated at 350A and also programmable, can provide non-critical load shedding when operating on batteries. When the LVBD option and battery breakers are not required the maximum number of available load breakers increases to 23.
