Allen Bradley 1336-BR-SP5A SCR Bridge Rectifier Assembly

FAQ

Q1: What is the Allen-Bradley 1336-BR-SP5A used for?
A: The 1336-BR-SP5A is an SCR bridge rectifier assembly used in Allen-Bradley 1336 drives to convert AC input power into DC bus power required by the drive inverter section.

Q2: Which Allen-Bradley drives are compatible with the 1336-BR-SP5A?
A: It is designed for 230V Allen-Bradley 1336 STE Series A-D and 1336 FORCE Series A drives.

Q3: Is the 1336-BR-SP5A a complete variable frequency drive?
A: No. It is only a replacement power component installed inside compatible 1336 drive assemblies.

Q4: What is the main function of the SCR bridge rectifier?
A: The SCR bridge rectifier controls the conversion of incoming AC power into DC voltage, supplying the drive’s DC bus for motor control operation.

Q5: Is the 1336-BR-SP5A still available from Rockwell Automation?
A: The 1336-BR-SP5A is listed as an obsolete spare part and has been replaced by a newer spare part version, such as 1336-BR-SP6A.

Q6: What are the dimensions and weight of the 1336-BR-SP5A?
A: The approximate dimensions are 150 × 100 × 60 mm, and the weight is approximately 0.8 kg. Actual values may vary depending on hardware revision and packaging.

Q7: Can the 1336-BR-SP5A replace other rectifier assemblies?
A: Replacement should only be performed after confirming the drive model, voltage rating, SCR configuration, mounting style, and original part number.

Q8: What should be checked before installing the 1336-BR-SP5A?
A: Verify the drive voltage rating, inspect power connections, confirm the replacement part number, discharge the DC bus voltage, and follow proper electrical safety procedures before installation.
