Description
The DC PowerCube 48 VDC – 80 A can deliver up to 4.3 kW, enough to charge batteries and battery banks quickly whilst still providing the various DC and AC loads with power for all equipment on marine and mobile/off-grid applications. The DC PowerCube 48 VDC – 80 A can even be used as a power supply, without batteries, as the smooth output voltage is incredibly uniform and ripple free.
