Information About ACS320-03U-12A5-4
The ACS320-03U-12A5-4 is an ACS320 series microdrive developed for HVAC equipment manufacturers and building services installations. Its R3 frame incorporates an IP20 enclosure for installation within a suitable control cabinet. Compatible operator interfaces include the optional ACS-CP-C basic panel and ACH-CP-B HVAC assistant panel. Embedded building automation protocols and dedicated pump and fan functions support integration into coordinated mechanical systems.
Key Features:
- Scalar Motor Control: Uses V/Hz regulation with selectable linear, squared, and user-defined voltage-to-frequency curves.
- Pump and Fan Coordination: Built-in control functions support applications operating multiple pumps or fans.
- Building Automation Connectivity: Embedded communication supports Modbus RTU, BACnet MS/TP, Johnson Controls N2, and Siemens FLN.
- Process Regulation: Two PID controllers support feedback-based adjustment of pressure, flow, or temperature.
- Energy Monitoring: Internal counters track energy consumption and calculate estimated savings.
- Pump Protection: Configurable monitoring can generate alarms or faults when abnormal operating conditions occur.
- Flexible Installation: Supports screw mounting or DIN rail installation within an appropriate enclosure.
- Optional Operator Panels: Supports basic parameter access or an HVAC assistant interface using compatible ABB panels.
The ACS320-03U-12A5-4 delivers the reliability and precision required for controlled HVAC pumping and ventilation.
