Technical Parameters Parameter Specification / Value Drive Series & Model ABB ACS550 General Purpose Drive Product Code ACS550-U1-072A-4 Rated Output Power 22 kW (30 HP) Rated Output Current 72 A (Output, three-phase) Input Supply Voltage 1-phase, 200 - 240 V AC (±10%) (*The "U1" denotes single-phase input*) Input Current Approx. 144 A (at rated load, single-phase) Input Supply Frequency 47 - 63 Hz Output Frequency Range 0.1 - 500 Hz Control Method Scalar Control (V/Hz) with flux optimization and Automatic Energy Optimization (AEO). Enclosure Class IP21 / UL Type 1 (Chassis Type). Requires installation in a suitable protective enclosure. Built-in EMC Filter Typically Class A (Standard). Limits electromagnetic interference. Fieldbus Interface Integrated Modbus RTU via RS-485. Digital/Analog I/O 3 Digital Inputs (DI) 1 Digital Output (DO) - Relay 1 Analog Input (AI) (0/4-20 mA or 0-10 V) 1 Analog Output (AO) (0/4-20 mA) Key Application Features • PID Controller • Sleep/Wake Function • Flying Start • Auto Energy Optimization (AEO) • Pump & Fan Macros Overload Capacity 110% of rated current for 60 seconds (typical for centrifugal loads). Braking Chopper Not internally integrated. Supports connection of an external brake resistor. Protection Features Comprehensive: Motor thermal (I²t) overload, short circuit, ground fault, over/under voltage, phase loss, etc. Derating Requirement Typically required due to single-phase input. Consult datasheet for exact derating curves based on load and ambient temperature. Operating Temperature -10°C to +40°C (without derating). Derating often required above 40°C. Mounting Wall mounting (vertical orientation recommended for optimal cooling). Approvals & Standards CE, cULus, RoHS, compliant with IEC 61800-5-1, EN 61800-3.
