Filed:

Sep 26, 2002

Appl. No.:

10/255743

Inventors:

Alfred R. Roman - Hendersonville TN
Michael Hardy - Nashville TN
Wayne Estes - Nashville TN
Daniel White - Franklin TN
Jerry Black - Murfreesboro TN

Assignee:

Chromalox, Inc. - Pittsburgh PA

International Classification:

H05K 720

US Classification:

361697, 361690, 361695, 174 161, 174 163, 165 803

Abstract:

A power controller generally includes a switching device and a heat sink in contact with the switching device for dissipating heat generated by the switching device. The heat sink may include a base and a plurality of fins extending from the base. The power controller may include a fan for forcing cooling air toward the heat sink and an air guide mounted to the heat sink for dividing the cooling air such that cooling air flows over the top of the heat sink and cooling air flows through the fins of the heat sink. The power controller may include multiple heat sinks and one or more temperature sensors.

Assignee:

Chromalox, Inc. - Pittsburgh PA

International Classification:

H02B 126

US Classification:

361622, 361624, 361631

Abstract:

A power controller generally includes a first switching device and a first bus bar mounted to the first switching device such that wiring may enter and exit the power controller. The first bus bar may have a face plate that extends at least partially above opposed side plates of the power controller and a mounting plate in electrical contact with the first switching device. A power controller assembly generally includes a power controller having one or more bus bars and a cover having a top surface, opposed end surfaces, and opposed side surfaces for attaching to and enclosing the power controller. The opposed end surfaces may have one or more windows through which wiring may pass and connect to one or more of the bus bars of the power controller.

Filed:

Apr 26, 1995

Appl. No.:

8/430807

Inventors:

Wayne S. Estes - Nashville TN
Carl D. Russell - Watertown TN

Assignee:

Emerson Electric Co. - St. Louis MO

International Classification:

G05F 110
H02H 900

US Classification:

323239

Abstract:

A power controller (10) and a method for supplying power to a power distribution network (N) in which power from a polyphase source (G) is routed to using equipment (E) connected to the network through the power controller. A plurality of solid-state power devices (82) switch each separate phase of the polyphase power to the equipment. A firing circuit (14) controls gating of the switches to route the power. Fuses (F) are connected between the switches and the using equipment to interrupt power flow to the equipment if excessive current begins to be drawn. Circuit breakers (74) are connected between the power source and the switches to interrupt current flow to the equipment if excessive current is drawn. A control unit (20) controls operation of the controller. The firing circuit includes a master firing unit (164a) and a slave firing unit (164b).

Abstract:

A power controller (10) for supplying power to a power distribution network (N) in which power from a polyphase source (G) is routed to using equipment (E) connected to the network through the power controller. A plurality of solid-state power devices (82) switch each separate phase of the polyphase power to the equipment. A firing circuit (14) controls gating of the switches to route the power. Fuses (F) are connected between the switches and the using equipment to interrupt power flow to the equipment if excessive current begins to be drawn. A con, roller (20) controls a shutdown sequence employed by the controller to eliminate current spiking at shutdown. The various components are housed in an enclosure (22) which includes a mounting structure (56) for mounting the aforesaid components. A cooling system (26) employs a fan (88) for directing air flow through the mounting structure to cool the components. The circuit breaker and fuse mounting configurations are such as to allow the enclosure to be more compact than previous, similar enclosures so to provide a smaller, cheaper, more versatile power controller installation.
