Everything You Need to Know About DC Power Systems
Facility managers can invest in DC power systems to deliver uninterrupted power without sacrificing efficiency. Other power solutions such as alternating current (AC) are less
A direct current uninterruptible power supply (DC UPS) provides that. This guide provides information about DC uninterruptible power supplies. What Is a DC UPS? A DC UPS is a power system that provides uninterrupted direct current power when the primary power source is disrupted.
Using earth ground as a reference point, the output of a DC supply can be "X" number of volts above ground (positive polarity) or "X" number of volts below ground (negative polarity). Another way of explaining this, is as a positive supply can source (provide) current, while a negative supply can sink (accept) current.
An uninterruptible power system (UPS) uses DC power to provide an emergency supply to your facility. Most UPSs convert AC to DC and sends the converted electricity to batteries and backup systems. Then they are ready to provide temporary support during an outage.
Positive polarity, negative polarity, reversible polarity; why is this important when I purchase a supply? DC sources are polarity specific. Using earth ground as a reference point, the output of a DC supply can be "X" number of volts above ground (positive polarity) or "X" number of volts below ground (negative polarity).
