Allen-Bradley|1336-BDB-SP49D| Drive Module 

【Product Overview】

The Allen-Bradley 1336-BDB-SP49D is a specialized Gate Driver Board (Internal PCB) designed specifically for the 1336 PLUS and 1336 IMPACT adjustable frequency AC drive series. It is not a complete drive unit, but the "Engine Room" of the inverter, responsible for controlling the power flow to the motor. As a specialist in Allen-Bradley VFD spare parts, we provide this original board to help you restore your Industrial motor drive controller without the need for a full system replacement.

【Technical & System Logic】

To understand the 1336-BDB-SP49D, you must see its position within the drive architecture:

• The Location: This board is mounted directly above the IGBT power modules inside the 1336 PLUS drive chassis.

• The Bridge Role: It acts as the critical interface between the low-voltage control logic and the high-voltage power section.

• The Operation: It receives firing commands and converts them into high-current pulses to trigger the IGBTs. It also monitors the "Health" of the power section—if it detects an IGBT fault, the SP49D instantly sends a trip signal to the main controller to prevent a catastrophic explosion.

【Selection & Comparison Advice (Finding the Right Board)】

In the 1336-BDB series variable frequency drive family, the "SP" number is linked to the power rating (HP/kW) and the physical frame size. Based on our Model comparison, here is how to choose:

• Select 1336-BDB-SP49D: Typically for Medium Horsepower 460V drives (Frame C/D). This is our most requested Engine speed controller in stock.

• Select 1336-BDB-SP56C: Often used for High Horsepower configurations or specific voltage revisions. It is physically larger than the SP49D.

• Select 1336-BDB-SP44D / SP45D: These are usually designed for Low to Medium power 1336 PLUS II units. They have different gate drive current outputs.

• Select 1336-BDB-SP43D: Specifically for Low Horsepower applications.

• Important: Using an incorrect board (e.g., putting an SP43D where an SP49D should be) will lead to gate-drive failure. We assist you in checking your drive's nameplate to ensure 100% match.

【Product Core Advantages】

• Targeted Repair: By replacing only the 1336-BDB-SP49D Gate Driver, you can fix "Drive Won't Start" or "Gate Fault" errors at a fraction of the cost of a new inverter.

• OEM System Integrity: As an OEM original Allen-Bradley part, it maintains the original safety timings and protection curves of your 1336 system.

• Ready for Heavy Duty: Built to handle the electrical noise and heat inside manufacturing line drive cabinets.

【FAQ for Middlemen & Traders】

Q: Is this a complete Variable Frequency Drive (VFD)?

A: No, this is the Gate Driver Board (a replacement PCB) that goes inside the 1336 PLUS VFD.

Q: Can I use SP49D to replace other 1336-BDB boards?

A: Only if the part numbers match. Each "SP" number is designed for a specific drive power rating. We provide Compatibility service to help you check.

Q: My client has a "Line Down" emergency. How fast can you ship?

A: We have 1336-BDB-SP49D Ready Stock. We offer International shipping industrial drives via DHL/FedEx, typically arriving in 3-5 days to most regions.
