Allen Bradley 1333-DAA Used Surplus

The Allen-Bradley 1333-DAA Adjustable Frequency AC Drive is a variable frequency drive with both 3-phase and single-phase ratings. It provides reliable motor control in a variety of industrial applications. This drive, like all drives in the 1333 family of VFDs, provides output motor control via V/Hz and Pulse width modulated control which provides speed control by adjusting motor frequency, and it is fitted with a Type 1 (NEMA) rated enclosure suitable for hazardous industrial conditions. The 1333-DAA has a standard 3-phase rating of 7.5 Horsepower (5.5 kW), with 27 Amps of an input current and 10.8KVA of input power at 230 Volts AC nominal input voltage, and it also has a 24 Amps with 9.6KVA output current and power at 230 Volts AC. This drive also has a single-phase de-rating rating of 3 Horsepower, with 21.4 Amps and 4.9KVA input current and power at 230 Volts AC, and 11.4 Amps and 4.4KVA output current and power at 230 Volts AC. The 1333-DAA has an input voltage range of 200 Volts AC to 230 Volts AC (1 or 3-phase at 50 to 60 Hertz, and it provides over-voltage plus under voltage DC trips of 430 Volts DC and 160 Volts DC, respectively. The 1333-DAA has a load-dependent power loss ride thru time (the default time is 15 milliseconds), with a control ride-thru time of 100 milliseconds which is also load-dependent, and it offers a BUS overcurrent trip of up to 200% IET.

The 1333-DAA has a sinusoidal PWM output waveform, with a programmable output voltage range between 0 and the rated input (230 Volts AC), and it has an output frequency with a programmable range between 0 to 400 Hertz. The 1333-DAA has ± 0.5% frequency regulation, and it has 4 independent deceleration and acceleration times, each programmable from 0.1 to 1600 seconds. This drive has a stall protection of 140%, and it has a 0 to 40% output boost at 1% adjustable increments. It has an overload capability of 140% for 60 seconds, and it can detect and prevent ground output faults. It has both digital and analog frequency control inputs, and it has standard contact outputs with standard 0 to 10 Volts DC or 4 to 20mA analog outputs. The 1333-DAA has an operating temperature range of 14 to 122 degrees Fahrenheit, with a non-operating limit of –13 to 149 degrees Fahrenheit at 5 to 95% non-condensing relative humidity, and it is designed for use at 3,300 feet without de-rating.
