TENTATIVE Powerex, Inc., 200 Hillis Street, Youngwood, Pennsylvania 15697-1800 (724) 925-7272 PP300T120 TM POW-R-PAK 300A / 1200V 3 phase IGBT Assembly Description: TM The Powerex POW-R-PAK is a configurable IGBT based power assembly that may be used as a converter, chopper, half or full bridge, or three phase inverter for motor control, power supply, UPS or other power conversion applications. The power assembly is mounted on a forced aircooled heatsink and features state-of-the-art Powerex F-series trench gate IGBTs with low conduction and switching losses for high efficiency operation. The TM POW-R-PAK includes a low inductance laminated bus structure, optically isolated gate drive interfaces, isolated gate drive power supplies, and a DC-link capacitor bank. The control board provides a simple user interface along with built-in protection features including overvoltage, undervoltage lockout, overcurrent, overtemperature, and short circuit detection. Depending on application characteristics the TM POW-R-PAK is suitable for operation with DC bus voltages up to 800VDC and switching frequencies above 20kHz.
