Parameters: Model Number: ABB ACS550-01-04A1-4 Rated Output Power: 1.1 kW (approximately 1.5 HP) Input Voltage Range: 380–480 V, 3-phase power supply Rated Input Current: 2.6 A (at 380 V) Frequency Range: 0 to 500 Hz Control Method: V/f (Volts per Hertz) Control: A basic method of motor control, suitable for most industrial motor-driven applications. Sensorless Vector Control (optional): Provides more precise motor control at low speeds without the need for an external sensor. Motor Control: Suitable for both constant torque and variable torque applications, allowing for flexible motor control. Ambient Temperature Range: -10°C to +50°C (at full rated current) Protection Class: IP20 (for indoor use; additional external protection kits are available for more challenging environments) Cooling: Forced air cooling (fan inside the drive) Efficiency: Typically 97%, which ensures energy-efficient operation. Dimensions (H x W x D): Approx. 220 x 150 x 130 mm (varies by configuration) Weight: Approx. 2.0 kg Control Voltage: 24 V DC (for control and auxiliary circuits) Mounting: Panel or wall mountable (with standard mounting holes for easy installation) Communication Protocols: Modbus RTU (for integration with PLCs and automation systems) Optional Profibus DP, DeviceNet, and Ethernet/IP (depending on configuration) Keypad: Integrated keypad with digital display for easy setup, monitoring, and diagnostics. Built-in Application Macros: Pre-programmed settings for pumps, fans, and conveyors, simplifying installation and setup.
