ABB ACS355-03E-04A1-4 VFD 2HP 1.5kW 3-Phase 380-480V Sensorless Vector Drive

ABB ACS355-03E-04A1-4 VFD 2HP 1.5kW 3-Phase 380-480V Sensorless Vector Drive

The ABB ACS355-03E-04A1-4 is a compact variable frequency drive (VFD) rated at 1.5 kW (2 HP), designed for three-phase AC motor control in industrial machinery applications. It uses sensorless vector control to manage both asynchronous (induction) motors and permanent magnet motors without the need for a shaft encoder. This unit carries the MUL1 option module and is rated IP20 / UL Open Type, making it suited for cabinet or panel installation.

Applications

The ABB ACS355 series is a micro drive intended for machine builder and OEM applications including material handling conveyors, food and beverage processing lines, and the processing of rubber, plastic, and wood. As a variable frequency drive, it controls AC motor speed and torque by varying the output frequency and voltage, which reduces energy consumption and mechanical stress compared to across-the-line starting. The sensorless vector control mode gives it strong low-speed torque capability without requiring a feedback encoder — useful in applications where precise speed regulation is needed but adding an encoder is not practical. The ACS355 family dates from the 2000s–2010s and remains a widely deployed drive in light industrial and packaging machinery worldwide. It is a drop-in replacement candidate for other ACS355 units of the same rating and is compatible with ABB's range of fieldbus adapter modules for integration into PLC-controlled systems.

Condition: Used
This ABB ACS355-03E-04A1-4 2HP Variable Frequency Drive has been inspected and appears to be in good condition. It was pulled from a factory that closed. The unit shows normal wear consistent with previous industrial use. The enclosure, terminal block, and indicator LEDs are intact and show no signs of physical damage.
