Patent number: 8339759Abstract: A relocatable power tap that includes a surge protector. The surge protector provides three modes of transient voltage surge protection while limiting leakage current caused by the relocatable power tap to less than a current limit value (e.g., 100 micro-amperes [“?A”]). The surge protector includes a first transient voltage clamp connected between a line conductor and a neutral conductor, a second transient voltage clamp connected between the line conductor and a ground conductor, and a third transient voltage clamp connected between the neutral conductor and the ground conductor. The transient voltage clamps are, for example, varistors having non-linear current-voltage characteristics. In the presence of voltages that exceed the clamping threshold voltages of the transient voltage clamps, the transient voltage clamps are configured to conduct the current associated with the transient voltage.Type: GrantFiled: November 29, 2010Date of Patent: December 25, 2012Assignee: Trippe Manufacturing Co.Inventor: Eugene A.

Patent number: 7687936Abstract: An uninterruptible power supply having an input connector for receiving AC power from a centralized source of electric power such as a power grid of an electric utility company, a first electric outlet, and a second electric outlet for delivering AC power, a first switch for selectively allowing AC power therethrough to the first outlet, a second switch for selectively allowing AC power therethrough to the second outlet: and a controller operable to control the second switch so that AC power is delivered to the second outlet a predetermined amount of time after AC power is delivered to the first outlet (i.e., after a time delay).Type: GrantFiled: March 21, 2008Date of Patent: March 30, 2010Assignee: Trippe Manufacturing Co.Inventors: Dennis I. Mariasis, James C. Folk, Paul J. Dickerson

Patent number: 7375939Abstract: A relocatable power tap having a plug configured to connect to a source of AC power and at least one receptacle. The relocatable power tap also includes a power supply connected to the plug and configured to convert an AC signal to a DC signal, and a detector connected to the plug and configured to determine the existence of ground and polarity faults. The detector includes a first current-controlled switch configured to turn on if an open ground or polarity fault exists. A power switch is controlled by the detector. The power switch is connected to the power supply, and configured to communicate AC power from the source of AC power to the at least one receptacle based on whether a ground or polarity fault exists.Type: GrantFiled: August 21, 2006Date of Patent: May 20, 2008Assignee: Trippe Manufacturing Co.Inventor: Eugene A. Weil
