Allen-Bradley 1336-140550

The Allen-Bradley 1336-140550 Bus Capacitor Kit is expertly engineered for 1336 series AC drives, effectively supporting power ratings from 75 to 200 horsepower across specified rating codes. This vital component serves as the primary storage for DC voltage and operates seamlessly at temperatures up to 60 degrees Celsius. Designed for convenience, it is securely housed in the chassis’s lower left corner, protected by plastic guards for easy access, eliminating the need to remove the base driver mounting plate. These capacitors ensure continued drive functionality by retaining charge even when powered off, necessitating a safety wait period of at least 10 minutes before any maintenance. Typically prompted by a “Bus Charging” alarm, maintenance is essential for inspecting and potentially replacing capacitors and balancing resistors to uphold optimal performance and voltage levels.
