DC Power Systems

DC power systems serve as the foundational backbone for power infrastructure in critical telecommunications and industrial applications. Their significance lies in ensuring a stable, reliable, and efficient power supply for vital equipment within these sectors. A typical DC power system comprises AC/DC rectifier modules for charging batteries and powering electronic loads, batteries for energy storage, DC distribution, Site Controller for system monitoring and control, and optionally, Solar MPPTs, DC-DC converters, or inverters for providing an uninterruptible power supply (UPS).



Powerbox stands as a leading provider with extensive experience in supplying DC power systems to the Australian market. Our comprehensive range of DC power solutions can be tailored to meet individual customer requirements, whether it be via a standard, semi-modified or complete turnkey platform.
