ACS550-01-072A-4 ABB Variable Frequency Inverter -40 °C To 85 °C 0.72/Step 7.5KW
ACS550-01-072A-4 Description
The ACS550-01-072A-4 is a general-purpose low-voltage AC drive from ABB’s ACS550 series, designed for variable-speed control of three-phase induction motors. It features a compact, wall-mounted design with robust vector control and scalar (V/Hz) control capabilities, delivering reliable performance for industrial automation applications. With a rated output current of 72 A, it supports a normal power rating of 37 kW (49 HP) and a heavy-duty power rating of 30 kW (40 HP) for 400V, 4-pole motors. Ideal for pump, fan, conveyor, and HVAC systems, it combines ease of use with energy efficiency and comprehensive protection.
ACS550-01-072A-4 Key Features
- Dual Control Modes: Scalar (V/Hz) for simple applications and open-loop vector control for high dynamic performance, precise speed regulation, and torque control.
- High Efficiency: Achieves IE2 efficiency level with low standby loss (17 W), reducing energy consumption and operational costs.
- Integrated Safety & Protection: Built-in braking chopper for dynamic braking, overcurrent/overvoltage/undervoltage/overtemperature protection, and ground fault detection ensures safe operation.
- Advanced Communication: Standard RS-485 interface with Modbus RTU protocol; optional fieldbus adapters (e.g., PROFIBUS, DeviceNet, EtherNet/IP) for seamless integration with PLCs and SCADA systems.
- Flexible I/O Configuration: 6 programmable digital inputs, 2 analog inputs (0–10 V/4–20 mA), 2 analog outputs, and 3 relay outputs for versatile control and monitoring.
- User-Friendly Operation: Equipped with a backlit LCD control panel (basic or standard) for local control, parameter setting, and fault diagnosis. Supports FlashDrop for fast parameter download and setup.
- Robust Design: Book-size metal enclosure with IP20/IP54 protection (depending on configuration), forced air cooling, and resistance to industrial vibration and humidity.
- Global Certifications: Compliant with CE, UL, and RoHS standards, ensuring suitability for international markets.
