160S-AA02NSF1

Allen Bradley’s 160S-AA02NSF1 variable speed drive belongs to the 160 Series of variable speed drives; these drives are widely used in the industry, often times with rotation machines, compressors, or motors. The 160S-AA02NSF1 variable speed drive is a single-phase drive, which operates with an input voltage in the range of 200 to 240 Volts AC, at a frequency between 50 and 60 Hertz. It has a motor rating of 0.37 kW (0.5 HP) and a maximum output Amperage of 2.3. Both the voltage and the frequency are adjustable on this drive, which operates with an efficiency around 97%. This module also offers protective features, such as sensors that trip if the ambient temperature exceeds the 95 degree Celsius maximum, as well as an output short circuit, a faultless ride through, and an over/under voltage, which basically monitors the DC Bus Voltage in order to provide a safer operation. In terms of control features, the Allen-Bradley 160S-AA02NSF1 variable speed drive features a programmable Volts per Hertz ratio and an adjustable carrier frequency of 2 to 8 kHz, along with motor protection and stopping modes in 4 programmable models.

The Allen-Bradley 160S-AA02NSF1 variable speed drive is protected by a NEMA IP20 open enclosure, which protects the unit from external particles and has an analog signal follower integrated. To install this 160S-AA02NSF1 variable speed drive, start by placing the unit in a vertical position, as near as possible to the motor, to prevent some reflected wave phenomena because of long motor cables. Users should leave a space between the sides of the unit and the cabinet, in order to provide a means for ventilation. The necessary ventilation of this unit can be achieved in a number of ways, either by the convection method, for which it requires an air flow space or by use of the integrated cooler fan, which will automatically trip when the unit exceeds the 50 degree Celsius maximum while the unit is operating.
