Product Description
The Allen-Bradley 1336-R1-SP4A is a replacement snubber resistor or PC board kit for the power supplies, modules, and snubber resistor inverters of Allen-Bradley 1336 series AC drives (FORCE, IMPACT, PLUS II, and PLUS). These variable frequency drives, with output power ratings from 0.37 to 597 kilowatts, use the 1336-R1-SP4A to suppress voltage spikes caused by inductance when switches open. Compatible with Frame F drives, each power supply module requires three kits. This snubber resistor is suitable for AC drives with output power ratings up to 450 horsepower and high internal voltages/currents. Installation and servicing should only be performed by technicians experienced with Allen-Bradley 1336 AC drives, ensuring bus capacitors are fully discharged beforehand to prevent electric shock.
Is Your Device Showing These Signs?
The Allen Bradley 1336-R1-SP4A AC drive commonly experiences issues such as blown power semiconductors (IGBTs, diodes), capacitor failures within the DC bus, and problems with the control board. These failures manifest as over-current faults, over-voltage faults, or communication errors. Repair involves replacing damaged components, often requiring recalibration of the drive parameters and thorough testing to ensure proper functionality and prevent recurrence of faults. Firmware corruption also occurs, necessitating reflashing the EEPROM with the correct software version.

Our Repair Process for the
1336-R1-SP4A
Our repair process for the Allen Bradley 1336-R1-SP4A AC drive begins with a comprehensive evaluation to pinpoint the failure. We address common issues such as blown power semiconductors (IGBTs, diodes), capacitor failures in the DC bus, and control board malfunctions, which present as over-current faults, over-voltage faults, or communication errors. Repair includes the replacement of all damaged components, followed by a mandatory recalibration of drive parameters. We then conduct thorough testing to guarantee proper functionality and prevent fault recurrence. In cases of firmware corruption, we reflash the EEPROM with the correct software version to restore operational integrity.
