Allen-Bradley 1336-SN-SP21A

The Allen-Bradley 1336-SN-SP21A PCB inverter serves as an essential precharge snubber board for the 1336 Impact, Force, Plus, and Plus II AC drive series. Designed to mitigate voltage transients, this component is strategically installed near the drive's heatsink, ensuring optimal performance and voltage stability. Compatible with C frame drives that have power outputs between 20 and 30 horsepower at 460 volts AC, it is vital for providing reliable functionality. When replacing the snubber board, always disconnect power and perform thorough testing with a meter to confirm its operational integrity, facilitating smooth integration within the power module.
