Nextek's line of Power Hub Drivers (PHDs) are used as the centralized source of highly efficient DC power that is then simply distributed to the appropriate DC lighting loads. By incorporating DC Microgrid technology, the use of expensive energy becomes signifcantly improved while simultaneously eliminating the multiple assorted smaller power supplies that ultimately end up in landfills. The bulk of the installation consists of distributing safe-to-the touch Class II wiring and devices. This work can be performed by less expensive field personnel. With the increased ease and speed of a DC installation, combined with use of less expensive labor, the savings associated with installation of Nextek's DC solution is significant.
