DC Power Supply Integrates AC and Renewables

Nextek PhD provides AC-to-DC power at the building scale, integrates renewable energy, and can even save on first costs.

As low-voltage LED lighting becomes the norm in our buildings, a power struggle has begun.

These LEDs—and much of our other commercial equipment—use direct current (DC), while our electricity grid supplies alternating current (AC—see The Death and Rebirth of DC Power). When you consider that onsite renewables also generate DC power, then the case for converting from AC to DC at a building scale rather than an appliance scale is compelling.
