The Allen-Bradley 1305-BA03A is an Adjustable Frequency AC drive. In industrial terminology, this product may also be referred to as Variable Frequency Drive (VFD), Variable Speed Drive (VSD), Frequency Inverter and simply an inverter. These terminologies refer to an an industrial equipment that is coupled to an AC motor to control the Rotation Speed, Torque as well as implement protective start-up and shutdown and lower down power consumption.

The 1305-BA03A is capable of implementing basic to advanced motor control. Basic motor control includes START / STOP; FORWARD / REVERSE / JOG; REMOTE / MANUAL operation. For advanced motor control, this drive is capable of Standard Boost V/Hz, Standard Volts/Hz and Custom Volts/Hz control methods which are ideal control method for speed control. For motor protective start-up and shutdown, related parameters are Accel/Decel Time, Ramp to Stop and S-Curve Acceleration.

This drive operates when supplied with an input supply voltage of 380-460V, 3-phase and input current of 2.2 Amperes. It delivers an output voltage of 0-460VAC, 3-Phase, output current of 2.3 Amperes, output frequency of 0-400 Hz and applicable motor power output of 0.75 kW / 1HP.

This drive has Eight (8) discrete input channels with Five (5) channels fixed for START / STOP / DRIVE ENABLE /REVERSE signals and Three (3) fully programmable inputs; Two (2) programmable outputs; Two (2) analog inputs and One (1) analog output channel. It also has a separate external potentiometer speed reference. Appropriate potentiometer for use with this drive is a 10 k Ω Potentiometer, 2 Watts.

The 1305-BA03A operates in a voltage range of 340 to 500 Volts, with an apparent input power of 1.7 kilovolts AC. The power dissipation is 34 Watts, and the working efficiency is 97.5%. It has a NEMA 1 (IP30) standard enclosure and an ambient temperature around 50 degrees Celsius. The 1305-BA03A has a storage temperature range between 40 degrees Celsius to 70 degrees Celsius, with a relative humidity of 0 to 95% (non-condensing). The operational vibration of the 1305-BA03A is 1g. The 1305-BA03A has other features like a temperature sensor trips and the DC bus voltage that is monitored for insufficient or excess voltage. It also has a contact closure control input, with a configurable control wire, and an external potentiometer with a speed of up to 10 K ohms at 1 Watt, and an input impedance of 100 K ohms at a 10-bit resolution. The 1305-BA03A is a product with dimensions of 210 millimeters (8.27 inches) x 195millimeters (7.67 inches) x 175 millimeters (7.05 inches) and a weight of 4.2 kilograms (9.2 pounds).
