The Allen-Bradley 1336-BDB-SP19B PCB Gate Driver Board is a replacement gate drive board for the 480 Volts AC rated 1336 Force, Impact, Plus II, and Plus series drives. This gate driver board helps to amplify the low input signal into  high current input. It is located close to the drive board's main chassis and the main control board. The 1336-BDB-SP19B PCB is backward-compatible with previous PCB versions and it can serve as a replacement board for these boardversions. It is used with the 460 Volts AC and 40 to 50 Horsepower rated 1336 (STEF) series drives. It is also compatible with the frame ratings associated with these drive ratings and they can be installed on drives with or without enclosures. The 1336-BDB-SP19B PCB is supplied as an assembly kit with fastening screws and 1 gate drive board.

The 1336-BDB-SP19B PCB is tested for optimal operating conditions every time the power module is changed. Testing the board requires testing for open fuse conditions at the F1 and F3 fuses by using a testing meter that is set to resistance mode. It is also recommended that the users test VR1 to VR6 by using a meter set to the diode mode and compare these readings with standard table readings. All 1336 drive components (including the 1336-BDB-SP19B PCB) are field-installable and trouble-shooting guides like the 1336 PLUS-6.2, 1336 IMPACT-6.2, or 1336 FORCE-6.2 manuals are provided online to assist replacement and installations. The 1336-BDB-SP19B PCB is designed to operate within a 0 to 55 degrees Celsius temperature range, and it is suitable for environments with 5 to 95% non-condensing relative humidity range. It can function optimally at a maximum height of 1000 meters above sea level and it can withstand up to 15g of shock for 11 milliseconds.
