The Allen Bradley 1305-AA04A-HA2 1305 Adjustable Frequency AC Drives have a 1 Hp (0.75 kW), 200 to 240 Volts AC 3 A Single Phase rating or a 200 to 230 Volts AC 4.5A three Phase rating. It has an  IP30 (NEMA Type 1) enclosure and an HIM with Digital Up-Down Keys interface. The Allen Bradley 1305-AA04A-HA2 is an Adjustable Frequency Drive which works with single phase or three phase induction motors. These AC Drives produce a variable frequency three-phase or single-phase PWM (Pulse-Width Modulation) signal providing adjustable speed to AC induction motors. The drive can operate with 1 HP (0.75 kW) motor rating at three phases and 0.75 HP (0.55 kW) at one phase. This unit’s operating input voltages go from 200 to 240 Volts AC (180 to 265 Volts operational) for a one phase supply and from 200 to 230 Volts AC for a 3 phase supply. This module’s frequency can be adjusted from 0 to 400 Hertz in its programmable mode.

The 1305-AA04A-HA2 drive operates under a Sine Weighted PWM output algorithm with a carrier frequency adjustable in 100 Hertz increments from 2 kHz to 8 kHz. The environmental operating conditions for this module are from 0 to 50 degrees Celsius and it has a relative humidity of 0% to 95%. The Allen Bradley 1305-AA04A-HA2 has natural convection cooling method, and it supports vibration until 1 G limit. The 1305-AA04A-HA2 control inputs can be configurable from contact closure, Start-stop-Forward/reverse 2 or 3 wire input controls, switch activated presets values, a momentary non-maintained input (Jog), 10 K Ohms external speed potentiometer, analog input from 4 to 20 mA and analog voltage input from 0 to 10 Volts DC. The 1305-AA04A-HA2 drive also has an AC dynamic braking torque control feature. Its maximum current override limits are of 150% for 60 seconds and 200% for 2 seconds.
