Teardown: ABB ACS150 1 HP AC Motor Drive

01 April 2014
The following is an overview of a teardown analysis conducted by IHS Benchmarking.

The ACS150 AC motor drive from ABB (ACS150-03U-04A7-2) is a 1 HP unit that the company offers in its family of “component” drives. The ACS150 is available in cabinet-mounted (UL open) and wall-mounted (NEMA 1) versions. A recent teardown analysis of the cabinet-mounted version performed by IHS Teardown Services revealed that the ACS150 includes semiconductors made by Texas Instruments Inc., International Rectifier Inc., and On Semiconductor, among others.

The drive’s power consumption of 1.1 kW and 1 HP rating place it at the lower end of the low-voltage compact drive category. Drives in this category are characterized by small form factor, an enclosure safety rating of IP2X or higher, ratings to 25 kW/33 HP, limited fieldbus connectivity, and a simple user interface with limited programming capability. Primary application areas are pumps and fans.

While drives like the ACS150 have experienced wide acceptance, Jenalea Howell, Research Manager, Rotating Machines & Controls at IHS, says, “Manufacturers are beginning to add more advanced features to their compact drive offerings, such as Ethernet connectivity and more sophisticated programming.”

Summary points:

  • ABB ACS150 Series 1HP AC Drive (ABB ACS150-03U-04A7-2)
  • Wall- or cabinet-mounted versions available
  • 2.2” (diagonal) LCD monochrome display
  • Front panel potentiometer control
