摘要:
Systems and method for installing computer equipment and power distribution equipment in facilities is provided. In one aspect, the present invention provides an uninterruptible power supply system for use with a plurality of devices, each of the plurality of devices having a power input to receive power. The uninterruptible power supply system includes an equipment rack, an input to receive input power, a DC power source mounted in the equipment rack that provides DC power, an output that provides output power derived from at least one of the input power and the DC power, power distribution circuitry, mounted within the equipment rack, having a plurality of distribution devices each having an input coupled to the output to receive the output power, and a plurality of output power cables each having a first end coupled to one of the plurality of distribution devices to receive output power and a second end that mates with the power input of one of the plurality of devices.

“A blanking panel is provided for use with equipment racks or enclosures that house electronic components, and is configured to facilitate installation of the panel with a pair of vertical mounting rails or flanges of a rack or enclosure without the use of tools or other hardware. The blanking panel is constructed of one or more materials and/or defines one or more configurations such that when the blanking panel is installed into a rack or enclosure, portions of a body of the blanking panel interface with a surface of an equipment component or another blanking panel installed above or below the blanking panel to thereby form an air seal there between, which helps to reduce or prevent hot exhaust air from mixing with cooling air within a rack or enclosure, and further helps to reduce or prevent cooling air from bypassing equipment components.”

According to one aspect of the invention, a plug-in module is provided for installation in a power distribution assembly. In one embodiment, the plug-in module includes a housing, an electrical isolation and overcurrent protection device located in the housing and a current sensing device located in the housing and adapted to sense a current carried by the electrical isolation and overcurrent protection device. The plug-in module may further include a power cable including a first end that is pre-terminated at the plug-in module to connect the power cable to the electrical isolation and overcurrent protection device, and electrical contacts adapted to removably couple the plug-in module to a plurality of stationary electrical conductors of the power distribution assembly. According to one embodiment, the electrical isolation and overcurrent protection device includes a circuit breaker.
摘要:
A system and method for instantaneously determining the absolute position of a linear or rotary actuator. A code plate having a series of digital words thereon is associated with the linear or rotary actuator. A magnetic or optical code plate is utilized, each code plate provided with N tracks. M signal levels are associated with each point on every track. The use of M-ary signal levels would enable the instantaneous determination of the position of the code plate when power is supplied to the system.
