This semiconductor power switching kit is specifically engineered for the inverter and rectifier modules within the PowerFlex 7000 liquid-cooled or air-cooled drive systems. By providing gate drive circuit boards positioned close to the thyristors, the assembly establishes a low-inductance path that ensures highly efficient and uniform gating performance across the drive phases. Operating as a critical component in Pulse Width Modulated (PWM) Current Source Inverter (CSI) topologies, this semiconductor assembly handles high-capacity power conversion while supporting a fail-safe, non-rupture, and non-arc failure mode to preserve enclosure integrity under fault conditions.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatched Component Engineering\u003c\/strong\u003e: Supplied as a factory-calibrated pair of two SGCT devices to maintain precise electrical symmetry and balanced current sharing during conduction phases.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Gate Drive Integration\u003c\/strong\u003e: Features gate driver circuit boards directly attached to the semiconductor switches to optimize signal transmission timing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble-Sided Cooling Interfacing\u003c\/strong\u003e: Structured for placement between liquid-cooled chill blocks to manage extreme thermal dissipation requirements under full load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Peak Inverse Voltage Capacity\u003c\/strong\u003e: Designed to support series-connected topologies to increase the total voltage blocking capacity across the medium voltage network.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInverter phase modules and Pulse Width Modulated Rectifier (PWMR) structures within PowerFlex 7000 medium voltage drives.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty industrial motor control platforms requiring high-capacity \u003cstrong\u003e800A\u003c\/strong\u003e power switching.\u003c\/li\u003e\n\u003cli\u003eMarine propulsion, oil and gas extraction pumps, mining conveyors, and high-volume water treatment systems utilizing Current Source Inverter technology.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRockwell Automation \/ Allen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e81001-450-52-R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eComponent Description\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePKGD (2) SGCT MATCHED SET 800A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 Matched Devices\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e800A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSystem Compatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePowerFlex 7000 Medium Voltage AC Drive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTopology Support\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePulse Width Modulated (PWM) \/ Current Source Inverter (CSI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMedium Voltage Isolation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFiber Optic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrostatic Discharge Protection\u003c\/strong\u003e: This device contains highly sensitive electronics.
