ABB AFPS-11C Power Supply Board

Description

The ABB AFPS-11C Power Supply Board is a dedicated power component designed exclusively for the ACS800 series frequency converters, serving as a critical unit to deliver stable power and ensure consistent, reliable operation of the host equipment. It features advanced vector control variable frequency speed regulation technology, enabling precise motor control to boost energy efficiency and operational stability. The board also integrates matrix AC-AC frequency conversion technology, eliminating the intermediate DC link and bulky, high-cost electrolytic capacitors; this design achieves a power factor of 1, delivers sinusoidal input current, supports four-quadrant operation, and offers high system power density. Key performance metrics include a fast torque response of less than 2ms, speed accuracy of ±2% without PG feedback, torque accuracy of less than +3%, and the ability to output 150% to 200% torque at low speeds including zero speed. Electrical specifications include a 24V DC, 5A output to power the converter’s control circuitry. Built-in protection features guard against overvoltage and overcurrent damage to equipment. As a Field Replaceable Unit (FRU), it is easy to install and replace, reducing equipment downtime. It complies with RoHS standards for environmental friendliness, has a typical design lifespan of over 20 years, and has a net weight of approximately 1.45 kg and gross weight of 2 kg.
