160S-AA04NSF1P1

The 160S-AA04NSF1P1 is a variable frequency drive, manufactured by Allen Bradley. It is part of the 160 Smart Speed Controller Series; the “S” in the “160S” fraction of the catalog number represents a single-phase input voltage. The drive has a voltage rating of 200 to 240 volts with a maximum output of 4.5A; it has an open enclosure type with a rating of IP20. It also has an analog signal follower and a program keypad module. Just like the other 160 Smart Speed Controller Series drives, the nameplate of the 160S-AA04NSF1P1 is found on its side. It also displays the Serial Number, Date Code, and the Enclosure Rating. All 160 Smart Speed Controller Series drives share the same features, which include status LEDs, Ready/Fault indicating panels, a hinged finger guard, DC Bus Test Points, a Cooling Fan, Cooling Air Flow, and a DIN Latch. The Hinged Finger Guard provides easy access to load power and line terminals; the Indicating Panel is a standard feature of all Bulletin 160 drives from Allen Bradley, while the control functions are performed from the Control Terminal Block.

This module’s Status LED indicates if the DC bus has power and ready to run, while the Fault Indicator LED will light up if there any are errors in the system. The DC Bus Test Points allow users to test the DC Bus voltage when needed. Its Cooling Air Flow and Fan prevent the drive from overheating and the DIN Latch makes it easier to mount the drive on a DIN Rail. It is advisable that the 160S-AA04NSF1P1 be mounted on a flat and vertical surface. Screws should be used to secure the drive in place; the drive comes with a drilling template to make the task easier. The drive is compatible with any 35 millimeter DIN Rail. When installing the drive, maintain a 12.5-millimeter clearance on all sides.
