Allen-Bradley 1336-QPRE-SP1A

The Allen-Bradley 1336-QPRE-SP1A Pre-Charge Transistor Module is meticulously crafted for compatibility with 1336 Plus, Force, and Impact Drives, accommodating drive ratings from 7.5 to 30HP at both 230V AC and 460V AC. This module significantly enhances signal amplification and switching functions within the drive system. Featuring a direct connection to the heat sink through the bridge rectifier and a strategically placed snubber, it ensures peak operational efficiency. Installation is precise, requiring careful fastening with torque specifications ranging from 22 to 31lb-in for secure attachment to the chassis and heat sink. It also includes Terminal Block TB1 with clear markings for +DC and -DC, along with an LED indicator for real-time BUS status monitoring, making it a reliable choice for rigorous industrial environments.
