FAQs
Installation begins with confirming motor compatibility and power ratings (Pn 4 kW, 19.4 A). Connect the drive to the motor and to the control panel, configure the built-in PID and PFC settings for your application, and wire the device to the ABB control network if applicable. Ensure proper shielding, grounding, and protective device coordination to minimize startup transients and EMI effects.
Key specs include a 4 kW nominal power rating and a 19.4 A current draw, with integrated PID controllers and pump and fan control (PFC) designed for squared torque applications such as booster pumps and supply/return fans. It is a low-voltage drive intended for precise speed and torque control in HVAC and pumping scenarios.
Yes. The ACS310-03E-19A4 is explicitly designed for squared torque applications like booster pumps and supply/return fans, leveraging built-in PID and PFC to maintain intended pressure and flow while reducing energy use and mechanical stress.
The provided data does not specify explicit certifications. When purchasing, verify with ABB or the distributor for safety and regulatory markings (such as CE or regional equivalents) and any enclosure rating requirements. Always consult the datasheet and installation standards to ensure local compliance and safe operation in your environment.
Expect measurable energy savings from precise speed control, reduced wear due to smoother torque and start/stop, and lower maintenance costs through enhanced motor protection. The built-in PID and PFC help stabilize processes, which can translate to longer motor life and fewer unplanned outages in pumping and HVAC applications.
