Technical Parameters Parameter Specification / Value Brand & Series ABB ACS510 Product Model ACS510-01-038A-4 Rated Output Power 18.5 kW (25 HP) Rated Output Current 38 A (Decoded from "038A") Input Supply Voltage 3-phase, 200–240 V AC (±10%) Input Supply Frequency 47–63 Hz Output Frequency Range 0.1–500 Hz Control Method Scalar control (V/Hz) with Automatic Energy Optimization (AEO) and enhanced motor control features. Enclosure Rating IP21 / UL Type 1 (chassis type, must be installed in a protective cabinet). Built-in EMC Filter Not Standard at this power level. Typically requires an external EMC filter (e.g., ABB RFI filter) for compliance with emission standards. Fieldbus Interface Integrated Modbus RTU (RS-485). Optional fieldbus adapters (PROFIBUS, PROFINET, etc.) available. 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 • Dual PID controllers • Sleep/Wake & Catch a Spinning Motor • Automatic Energy Optimization (AEO) • Pump/Fan application macros • Flying Start • Customizable U/f curves Overload Capacity 110% of rated current for 60 seconds (for centrifugal loads like pumps and fans). Braking Chopper Not built-in. An external brake resistor and chopper unit are required for fast deceleration or overhauling loads. Cooling Method Forced air cooling (internal fan). Protection Features Comprehensive: Motor thermal (I²t) protection, short circuit, ground fault, over/under voltage, phase loss, drive overheating, etc. Operating Temperature -15°C to +40°C (without derating). Up to +50°C with current derating. Connection Terminals Screw terminals for power (R/L1, S/L2, T/L3, U, V, W, DC+, DC-, Brake) and control. Mounting Wall mounting (vertical orientation recommended for optimal cooling). Standards & Approvals CE, cULus, RoHS, IEC 61800-5-1, EN 61800-3.
