160-AA03NSF1

The 160-AA03NSF1 is a speed controller, belonging to the 160 Series of speed controllers, which are manufactured by Allen-Bradley. The Allen-Bradley 160-AA03NSF1 speed controller operates with an input voltage of 200 to 240 Volts and frequency of 50 to 60 Hertz. It has an external output of 0.55 kW (0.75 HP) and 3.0 A. The 160-AA03NSF1 speed controller has a power dissipation of 20 Watts and features an open style enclosure, which is basically a NEMA Type enclosure for industrial purposes (rated IP20), which protects the unit from harmful particles and enables it to operate within a temperature zone of 0 to 50 degrees Celsius (32 to 122 degrees Fahrenheit). The storage temperature range for this unit is between –40 and 85 degrees Celsius (–40 to 185 degrees Fahrenheit), and this speed controller can operate on high lands, so long as its altitude does not exceed 1,000 meters (or 3,300 feet). It also can withstand vibrations of 1.0 G and shocks of 15 G while it is operating. Procedure recommends that these units be placed as close to the motor-compressor as possible since a long length of motor cables can cause a gradual loss of power. When it comes to this module's control inputs, the Allen-Bradley 160-AA03NSF1 speed controller has an analog input impedance of 100 Ohms and 100k Ohms. It also comes with an external speed potentiometer of 10k Ohms and 2 Watts at a minimum.

The Allen-Bradley 160-AA03NSF1 speed controller has a number of protective features, such as temperature sensors, faultless ride through, protection in both start and run mode, control ride through, and the monitoring of the DC Bus when it is over and under voltage.
