BALDOR ACB530-U1-015A-4 Variable Frequency Drive

The Baldor-Reliance ACB530-U1-015A-4 is a 10 HP, 380–480 V three-phase AC variable frequency drive designed for industrial motor speed control. As part of the ACB530 family, it supports Volts-per-Hertz or sensorless vector control with a 150% peak overload capacity and built-in PID for precise torque and speed regulation, suitable for variable-torque, constant-torque, or constant-horsepower applications. Key specs include frame size R2, output current 15.4 A, input current 11.9 A, and a 48–63 Hz operating range. Mounting options cover UL Type 1 and UL Type 12 enclosures; it features a removable keypad for local operation, group-based parameter programming, and a quick-start assistant to simplify setup, plus a built-in braking transistor for interfacing with a remote braking resistor. The drive is a Baldor Reliance (ABB) product, designed to provide robust, configurable control for industrial motors in a compact, field-serviceable package.
