  • UPS power supply for low-voltage systems

    UPS power supply for low-voltage systems

    An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteri. Common power problemsThe primary role of any UPS is to provide short-term power when the input power source fails. However, most UPS units are also capable in varying degrees of correcting common utility power problems: 1. The three general categories of modern UPS systems are on-line, line-interactive and standby: • An online UPS uses a "double conversion" method of accepting AC input, to DC for pas.
