Allen-Bradley 1305-BA04A Variable Frequency Drive

The Allen-Bradley 1305-BA04A is a compact, 2 HP variable frequency drive designed to control a three-phase motor from a 380–460 V AC supply. It delivers up to 4 A of output current and roughly 1.5 kW of continuous power, matching a 2 HP motor for reliable speed control in small to medium industrial equipment. Housed in an IP30 (NEMA 1) enclosure, it’s intended for indoor installations and accepts 380–460 V three-phase input at 50/60 Hz. The drive provides a programmable output frequency, enabling a broad speed range up to 400 Hz so you can fine-tune motor performance and implement practical acceleration and deceleration behavior. As part of Allen-Bradley’s 1305 family, the BA04A model corresponds specifically to a 2 HP motor rating with a 4 A maximum output, offering a compact, economical solution when a modest horsepower drive is required for variable-speed control of compatible 2 HP motors. Typical applications include small conveyors, fans, pumps, and other equipment where reliable, adjustable-speed drive control is advantageous, all while integrating with Rockwell Automation’s standard hardware ecosystem.
