The Powerex 143-224-002H is a heavy-duty 1600 V, 250 A dual phase-control thyristor power module used in industrial AC power-control and critical-power equipment. Built in the Powerex POW-R-BLOKâ„¢ style, this module combines two high-current SCR devices in an electrically isolated package designed for controlled rectifiers, UPS input bridges, motor soft starters, AC voltage regulators, and other high-power switching applications.
With approximately 393 A RMS on-state capability and short-duration surge capability reaching approximately 8.8 kA, the 143-224-002H is designed to tolerate the substantial inrush currents and transient loads encountered in large industrial power systems. Its 1600 V repetitive blocking capability provides additional voltage headroom for line-powered equipment and high-energy rectifier stages.
The electrically isolated baseplate allows the module to mount directly to an appropriate heatsink while maintaining electrical separation between the semiconductor circuit and chassis. For legacy equipment replacement, the complete 143-224-002H identification, circuit configuration, terminal arrangement, gate connections, mounting dimensions, and electrical ratings should be compared with the original module before installation.
