The Allen-Bradley 1305-AA04A-HAP is a single/three-phase AC Drive manufactured by Rockwell Automation. It is a member of the 1305 series AC drives. The drive has the horsepower rating of 1HP (equivalent to 0.75 kW) which can be used for the speed control of 1-horsepower motors.

The 1305-AA04A-HAP supports a voltage of 200-240V AC for a single-phase supply and a 200-230V AC for a three-phase power supply. The motor’s output current rating is 4.5 A and this output amperage is for the given input voltage range. At an input voltage beyond the prescribed limit, the output current may be different for single phase and 3-phase supplies. The pulse-width modulation (PWM) frequency is 50-60 Hz.

The Allen-Bradley 1305-AA04A-HAP has a compact, space-saving design with dimensions measuring 120 x 195 x 140mm in width, height and depth (without the pot). However, the width of the drive with the pot measures 145.1mm. The 1305-AA04A-HAP comes in an IP30 NEMA Type 1 enclosure. The approximate shipment weight is 1.9 kg or 4.2 pounds.

The primary purpose of the 1305-AA04A-HAP AC drive is to ensure safe operation, increase productivity, and save energy. The drive’s adjustable frequency allows the precisely right amount of current to be delivered for smooth starting, acceleration, deceleration and stopping. The 1305-AA04A-HAP drive also uses its adjustable frequency to reduce the risk of damage to the machine from extreme voltage fluctuations.

As a precaution, users should make sure that the motor’s full-load amps (FLA) do not exceed the 1305-AA04A-HAP drive’s output current rating. The 1305-AA04A-HAP’s maximum operating temperature is 50 degrees Celsius. Its integrated Human Interface Module (HIM) is the ‘programmer only’ type of HIM. It does not support the ‘Controller’ functionality.
