The 1336-120881 is a replacement part for the Allen Bradley-Rockwell Automation 1336 adjustable frequency drives that are designed for top-class performance and their main purpose in an industrial environment is to control three-phase induction motors. These drives are, in comparison to other similar devices from other manufacturers, very easy to use and their microprocessor control operation principle makes them reliable and on point. The 1336 drives are mostly connected to speed control applications and are highly adjustable for achieving optimal performance from the controlled motor. The 1336 industrial grade drives are available with many different voltage ratings and nominal horsepower ratings so there are numerous options to choose from. Also, every drive from this line of products has an enclosure with ingress protection from IP20 to IP54 so the components that are inside the drive are safe and secured from dust, water splashes and other influences of a harsh industrial setting.

The 1336-120881 product code stands for a precharge board of the drive's precharge. Precharge is used in order to prevent damage to main components and to reduce electrical hazards which may occur. The precharge board for 1336 drives has a horsepower of 3 up to 30 Hp. The precharge board is part of a precharge assembly and it can easily be accessed by disconnecting ground wire and removing the connectors. There are some variations in regard to disassembly of the precharge to change the 1336-120881 board, mostly because there are different types of drive frames. In any case, the drives are designed for easy maintenance and removing parts to replace it with new ones is simplified. Connector location and orientation should be taken into consideration when the replacement of the board is performed. Even though Allen Bradley drives are high-quality products with long life, it is essential to stay prepared for replacement of parts if the drive seems to be faulty or not working at all.
