ABB ACS800-U1-0004-2P901 Variable Frequency Drive

ABB ACS800-U1-0004-2P901 Variable Frequency Drive is a compact, three-phase motor speed controller from ABB's ACS800-U1 family, designed to deliver precise, programmable control for small to mid-size machinery by modulating voltage and frequency to the motor. This unit is rated at roughly 2.2 kW (3 HP) output and is configured for a 208–240 V three-phase supply, with a nominal input current around 9.3 A and a 16 A fuse recommendation for the -0004-2 hardware variant, aligning with ABB's ACS800-01/U1 hardware guidelines. The -0004-2P901 suffix identifies the exact order/config combination within ABB's catalog for this size, ensuring the drive matches the intended control interface and electrical configuration used in light- to medium-duty automation projects. With ABB's drive architecture, the ACS800-U1 platform provides reliable, smooth ramping and motor protection features that help maintain consistent torque and speed, making this model a suitable choice when a low-voltage, compact VFD is needed to upgrade older variable-speed drives or to enable precise automation in panel-mounted or integrated control systems.
