A power system includes a base module including a system management controller (SMC) and a power distribution unit (PDU), an uninterruptible power supply (UPS) module including a UPS, and a battery module including a battery. The base module includes a first edge, and the battery module is detachable from UPS module in a direction perpendicular to the first edge.

Modular power system

According to at least one aspect embodiments herein provide a rack power system for providing DC power to equipment installed in a rack, comprising a first shelf containing a plurality of power supplies, each of the plurality of power supplies configured to receive AC power and to provide DC power to equipment installed in the rack, a second shelf containing a plurality of battery units, each of the plurality of battery units configured to provide DC power, and a controller coupled to the first shelf and the second shelf and configured to control each of the plurality of power supplies and configured to control each of the plurality of battery units.

Rack power system and method

A capacitive sensor system for detecting accumulation of dust in a filter of a HVAC system includes a first conductive mesh, a second conductive mesh, a first filter media disposed between the first conductive mesh and the second conductive mesh, and a circuit configured to measure a capacitance of a first capacitive sensor formed by the first conductive mesh, second conductive mesh, and the first filter media. The circuit further is configured to translate a measured capacitance to a dust level indicator frequency that is used to determine a frequency corresponding to level of dust.

Method and system for detecting dust accumulation in a HVAC filtering system

A method and an apparatus for controlling distribution of power. The apparatus is used for controlling application of power to a plurality of devices including at least one master device and at least one controlled device. The apparatus includes: a power inlet constructed and arranged to receive power from a power source; a plurality of power outlets including at least one master power outlet (M) and at least one controlled power outlet (S); and means for generating a power profile of the at least one master device electrically connected to the master power outlet, determining a characteristic of a stand-by power consumption level of the at least one master device and controlling a supply of power from the power inlet to the at least one controlled power outlet in response to a comparison of a characteristic of power delivered to the at least one master device with the characteristic of the stand-by power consumption level.

Method and apparatus for controlling distribution of power

Aspects of the invention are directed to apparatus and methods for controlling power distribution to a plurality of devices including a primary device and at least one secondary device, the primary device having at least a first mode of operation and a second mode of operation, with the second mode of operation being a lower power mode of operation than the first mode of operation.

Methods and systems described herein provide protection for sensitive circuits against power surges on power lines. A surge protector for protecting a load coupled to a power source is provided. The surge protector includes an input having a first node, a second node and a third node to respectfully couple to line, neutral, and ground connections of a power source, an output having a fourth node, a fifth node, and a sixth node for respectfully coupling to line, neutral and ground connections of the load, a first voltage limiting circuit coupled between the fourth node and the fifth node, a first inductor coupled between the first node and the fourth node, and a second voltage limiting circuit coupled between the first node and the second node.
