Patent number: 8489667Abstract: A vertical-mount network remote power management outlet strip embodiment of the present invention comprises a long, thin outlet strip body with several independently controllable power outlet sockets distributed along its length. A power input cord is provided at one end, and this supplies AC-operating power to relays associated with each of the power outlet sockets. The relays are each addressably controlled by a microprocessor connected to an internal I2C-bus serial communications channel. The power-on status of each relay output to the power outlet sockets is sensed and communicated back on the internal I2C-bus. A device-networking communications processor with an embedded operating system translates messages, status, and controls between the internal I2C-bus and an Ethernet port, and other external networks.Type: GrantFiled: May 9, 2005Date of Patent: July 16, 2013Assignee: Server Technology, Inc.Inventors: Carrel W.

Publication number: 20120319485Abstract: An automatic transfer switch for a power system receiving multiple alternating current sources and delivering multiple alternating current output is described. A transfer switch control circuit can sense a power loss in one or both AC sources. Each power supply can deliver current to drive a load but, if one of the power supplies fails, the other can supply power to drive both loads.Type: ApplicationFiled: March 20, 2012Publication date: December 20, 2012Applicant: SERVER TECHNOLOGY, INC.Inventors: Carrel W.

Patent number: 8321163Abstract: A power distribution unit (PDU) disposable in an electrical equipment rack. The PDU has a housing, a power input penetrating the housing, outlets in the housing, a processor disposed in the housing, voltage and current sensors, and a voltage calculation procedure communicable with the processor. The processor samples voltage and current waveforms and calculates RMS values and other power parameters. A method of managing electrical loads each drawing electrical power from a PDU includes repeatedly sampling voltage across and current flowing through each of the loads, calculating raw RMS values of voltage and current, and scaling the raw RMS values to obtain corrected RMS voltage and current values and other power parameters.Type: GrantFiled: March 4, 2010Date of Patent: November 27, 2012Assignee: Server Technology, Inc.Inventors: Carrel W.
