A motor drive or bus supply power conversion system includes a rectifier with at least one rectifier switch module for rectifying AC input power. A DC bus is connected to the rectifier and supplies DC output power. An optional inverter is connected to the DC bus and includes at least one inverter switch module for inverting the DC bus voltage to an AC output power. The at least one rectifier switch module and the at least one inverter switch module each include a base plate and a housing connected to the base plate. The housing defines an interior space that contains at least one semiconductor switch. Anti-corrosion features are provided including a conformal coating on printed circuit board assemblies, removable connector covers, dielectric grease coated connections, nano-coated fiber optic transceivers, and an exterior protective film wrap.

Power conversion system with enhanced protection for gaseous corrosive atmospheres

Protective cover devices for associated electrical connectors include a one-piece molded polymeric body including at least one of: (i) at least one stud that is closely slidably received into a corresponding socket of the connector; (ii) a skirt that comprises a recess that receives at least part of the electrical connector therein. The protective cover device is adapted to be engaged with the associated electrical connector to inhibit contact between a surrounding corrosive atmosphere and at least one electrical contact of the associated electrical connector.

Protective cover devices for protecting electrical connectors in industrial equipment

A motor drive or bus supply power conversion system includes a rectifier with at least one rectifier switch module for rectifying AC input power. A DC bus is connected to the rectifier and supplies DC output power. An optional inverter is connected to the DC bus and includes at least one inverter switch module for inverting the DC bus voltage to an AC output power. The at least one rectifier switch module and the at least one inverter switch module each include a base plate and a housing connected to the base plate. The housing defines an interior space that contains at least one semiconductor switch. A protective cover layer includes a corrosion protection material and divides the interior space into an inner sub-space located between the base plate and the protective cover layer and an outer sub-space located between the protective cover layer and the housing. The at least one semiconductor switch is located in the inner sub-space such that an atmosphere in the outer sub-space passes through the protective cover layer of corrosion protection material before entering the inner sub-space. Additional anti-corrosion features are provided including a conformal coating on printed circuit board assemblies, removable connector covers, dielectric grease coated connections, nano-coated fiber optic transceivers, and an exterior protective film wrap.

Systems, methods, and devices are provided for coupling a direct current (DC) pre-charging circuit to a motor drive. In one embodiment, an industrial automation device may include an enclosed module that may include a pre-charge circuit. The pre-charge circuit may pre-charge a direct current (DC) bus. Further, the DC bus may couple to an inverter. The enclosed module may also include a power input that may couple the pre-charge circuit to a DC power source and an electrical output structure that may couple the pre-charge circuit to the inverter. Additionally, the pre-charge circuit may be removeably coupled to the inverter and the DC power source via a sliding action of the enclosed module.

Systems and methods for manufacturing a pre-charge circuit module

A menu-driven manufacturing technique includes determining a product and product configuration, along with process steps to be carried out in manufacturing workstations. Display screens corresponding to the particular manufacturing process steps are accessed and displayed on monitors at the workstations to lead operators through the processes. Control circuitry may verify that the correct components and tools are utilized as called for by the various process steps. Powered tools and test setups may be integrated with the system to enable improved quality control.

Integrated menu-driven manufacturing method and system

A grommet and corresponding installation system includes a grommet body with an outer surface and a cord that is attached to and extends outwardly from the grommet body, along with a grommet installation tool having a cord-engaging end removably attached to the cord such that the tool can be manipulated to tighten the cord which radially compresses the grommet body, whereby the tool can be used to pull the grommet through a panel hole when the grommet body is in such radially compressed state.
