Detailed content

The A-B (Allen-Bradley) 1336-BDB-SP49D is a Gate Driver Printed Circuit Board designed for Allen-Bradley 1336 series adjustable frequency AC drives. It is used to control the switching signals of the inverter power devices, providing accurate gate drive pulses between the control circuitry and power semiconductor stage. The board is part of the 1336STEF spare parts family and is designed for high-power motor control applications.

The 1336-BDB-SP49D is specified for 575 VAC, 400 HP, G-frame 1336STEF drives and replaces earlier 1336-BDB-SP49A and 1336-BDB-SP49C versions. It is commonly used for maintenance and repair of legacy Allen-Bradley 1336 PLUS, PLUS II, FORCE, IMPACT, and related AC drive systems.
