Key Specifications Parameter Category Specification Drive Series/Model ACS310-03E-34A1-4 Rated Output Current 34 A Rated Output Power 15 kW (20 HP) Input Supply Voltage 380 - 480 V AC (± 10%), 3-phase Input Supply Phases 3-phase Output Voltage 0 - Input voltage Output Phases 3-phase Enclosure Rating IP20 / UL Open Type (Chassis). Requires installation in a protective cabinet. Cooling Method Self-cooled (with internal fan) Control Methods • Scalar Control (V/f) • ABB Direct Torque Control (DTC) for superior dynamic performance. Key Standard Features • Intelligent Pump and Fan Control (IPF): Includes auto-tuning for energy optimization, multi-pump control logic (lead/lag/alternation), dry pump protection, and anti-jam functions. • Embedded Application Programming: Built-in function blocks (timers, logic gates, comparators) for creating custom control logic without an external PLC. • Adaptive Program (AUP): Guides user through commissioning based on selected application. • Built-in Communication Protocols: Modbus RTU (RS-485) and BACnet MS/TP are standard for building automation integration. • LCD Keypad: Clear display with multi-language support and parameter copy function. • Integrated EMC Filter (Class A). • PID Controller: Advanced controller with sleep/wake, cascade control, and PID freeze functions. Protection Features • Motor thermal overload protection (I²t) • Pump/Fan-specific protection (dry pump, overload, underload) • Short circuit, ground fault, overcurrent, overvoltage protection • IGBT overtemperature protection • Automatic fault reset and restart Application Focus HVAC systems (fans, pumps), pressure boosting, water supply, cooling towers, and general fluid handling applications.
