ACS355-03E-12A5-4 ABB Variable Frequency Inverter 3~400/480VAC 0.4kW To 500kW
ACS355-03E-12A5-4 Description
The ABB ACS355-03E-12A5-4 is a compact, cost-effective AC drive (variable frequency drive, VFD) from the ABB Machinery Drive series, designed for basic motor speed control applications. It provides reliable and precise control of three-phase induction motors, offering a simple yet robust solution for a variety of standard industrial applications. Engineered for ease of use, it features a straightforward control panel and pre-defined application macros, making installation and commissioning quick and efficient. This drive is particularly suitable for applications in material handling, ventilation, and basic pump systems, where it enhances process efficiency, reduces energy consumption, and minimizes mechanical stress on equipment.
ACS355-03E-12A5-4 Features
-
Simplified Setup: Features an intuitive, multilingual control panel with a start-up wizard and built-in application macros for pumps, fans, and standard three-wire control, enabling rapid commissioning with minimal configuration.
-
Energy Saving Function: Includes an integrated "Energy Optimizer" feature that automatically adjusts motor voltage to match load demand, significantly reducing energy consumption in variable torque applications such as fans and pumps.
-
Compact and Robust Construction: Housed in a durable plastic case with an IP20/IP21 protection rating, the drive is designed for long-term reliability in typical industrial environments. Coated PCBs and quality components ensure resistance to dust and humidity.
-
Flexible Control and Connectivity: Offers standard digital and analog I/O for basic control signals, plus an integrated RS-485 interface for Modbus RTU communication. Optional plug-in modules are available for common fieldbus networks (e.g., Profibus DP, CANopen, BACnet MS/TP).
-
Comprehensive Protection: Provides essential motor and drive protection features, including overcurrent, overvoltage, motor overload, and short-circuit protection, along with fault history logging for easier troubleshooting.
-
Optional Safety: The Safe Torque Off (STO) safety function is available as an option, enabling integration into safety-related control systems in compliance with machinery safety standards (SIL 3, PL e).
ACS355-03E-12A5-4 Material and Applications
-
Material: The drive enclosure is made of high-strength, flame-retardant plastic (UL94-rated). Internal components include a metal heatsink for thermal management and printed circuit boards with a protective conformal coating to enhance durability in industrial settings.
-
Applications: Ideal for controlling fans, pumps, compressors, and basic material handling systems in HVAC, water treatment, packaging, and general light industrial automation.
