1333-BAA

The Allen Bradley 1333-BAA is a variable frequency drive that operates at an input voltage of 200 to 208 Volts of AC. The variable frequency drive also has a horsepower rating of 3.0 HP and a power rating of 2.2 kilowatts. The 1333-BAA accepts an input current of 14.0 Amperes and also provides an output current of 11.0 Amperes. The total heat dissipation rating for the 1333-BAA is around 853 BTU per hour; this belongs to Series D of the 1333 drives.

The 1333-BAA operates at a frequency of 50 to 60 Hertz with the maximum drive output frequency being dictated by the lowest values, which are set in either parameter 3, 15, 51, 53, or 54. These parameters cater to the frequency range, highest attainable frequency, frequency clamp (upper), bias, and gain frequency. The apparent input power rating is 4.8, 5.0, and 5.0 Amperes for the 200, 208, and 230 volts Alternating Current respectively in a 3-phase voltage supply. Also, in a 3-phase voltage supply, the 1333-BAA has an apparent output power of 3.8, 4.0, and 4.4 Amperes. When supplied with a single-phase voltage, the 1333-BAA has a Horsepower rating of 1.5 and a real power rating of 1.1 kilowatts.

The 1333-BAA accepts connections through the 8-point terminal block, which is situated at the bottom of the main control board. To avoid harmful effects when installing the 1333-BAA adjustable frequency drive, disconnect the power supply and any motor that may be connected. Qualified personnel should attend to the 1333-BAA variable frequency drive and for monitoring and troubleshooting, this drive has a display and LED indicators (Hz, alternate). To ease troubleshooting of the drive and or the motor connected to it, the display shows error codes. According to NEC guidelines, motor overload protection must be catered for in the motor branch circuit.
