The ABB ACS355-03E-38A0-4 is a compact low voltage AC drive designed specifically for machine building and industrial automation applications. It controls three-phase asynchronous AC induction motors and permanent magnet synchronous motors with a rated power of 18.5 kW and continuous output current of 38 A. The drive operates from a 380-480 V AC three-phase supply and features an integrated Safe Torque Off (STO) safety function compliant to SIL3, built-in braking chopper, and EMC filter. Designed for rapid commissioning, it includes FlashDrop pre-configuration capability, application macros, and panel assistants. The ACS355 supports sensorless vector control, offers motor protection functions, PID control, and frequency output up to 500 Hz. Ideal for food and beverage, material handling, textile, printing, rubber and plastics, and woodworking applications. The drive provides energy-efficient motor speed control with 50% overload capability for one minute every ten minutes.
