Description

The Allen-Bradley 1336-PB-SP2C is a precharge printed circuit board (PCB) designed for use within the 1336 series variable frequency drive systems. This component serves as a critical spare part for managing the DC bus precharge sequence, ensuring that inrush currents are limited during the initial power-up phase of the drive to protect internal capacitors and power electronics.

Features

Original Allen-Bradley replacement component
Specifically designed for 1336 series drive architecture
Facilitates controlled DC bus charging to prevent component stress
Direct replacement for specified 1336 drive configurations

Applications

This precharge board is utilized in industrial motor control applications where 1336 series drives are deployed. It is typically required during maintenance or repair of drives experiencing precharge circuit failures or DC bus charging faults.

Installation Guidelines

Ensure the drive is fully disconnected from all power sources and that the DC bus capacitors have been verified as discharged before attempting to access the internal electronics.
Use proper Electrostatic Discharge (ESD) protection, such as a grounded wrist strap, when handling the circuit board to prevent damage to sensitive components.
Carefully align the board with the mounting standoffs and ensure all connectors are fully seated before re-applying power.
Verify that no loose debris or foreign objects remain inside the drive chassis after installation.
