Extreme. Precise fault protection ensures unattended operation and peace of mind; accurate water-use timing control saves every kilowatt-hour of electricity and cherishes every drop of water.
Integration. Perfect system compatibility; versatile motor adaptation for multiple models; portable installation; and a variety of fully electronic control system solutions.
03 Scope of Application
♦ Secondary water supply applications in commercial properties, residential communities, and public venues; HVAC circulation applications;
♦ Water supply applications for construction sites and production processes.
04 Technical Parameters
♦ Power range: 1.5–22 kW;
♦ Input voltage: 380VAC ±10%;
♦ Compatible motors: asynchronous motor, synchronous reluctance motor, permanent-magnet synchronous motor;
♦ Main functions: Complete pump control functionality, various types of motor drives and protection, as well as detection and protection against ambient temperature and mechanical vibration.
05 Built-in Vibration Monitoring
In addition to the traditional motor self-tuning feature, the AS170PLUS incorporates a vibration calibration adjustment, enabling the monitored output values to synchronize with the measured values from high-value, professional inspection instruments. Subsequently, real-time vibration measurements can be uploaded to the host computer via CAN bus or MODBUS bus, allowing the operating conditions of the pump to be recorded and updated continuously.
06 Product Advantages
♦ The intelligent inverter with a PLC featuring a perpetual calendar function built-in allows for simple configuration of all required pump functions, ensuring perfect performance.
♦ IP54 protection rating, German UV-curing three-proof coating, temperature- and moisture-resistant, rugged and durable—equivalent to an integrated control cabinet;
♦ Built-in vibration monitoring and CAN bus enable real-time monitoring of the transfer pump’s wear and tear information;
♦ Silencer: The inverter operates silently, featuring specialized noise-reduction and quiet-running technology.
♦ High power factor and low input current make it highly adaptable to the renovation of older residential areas, opening up more business opportunities.
♦ No need for complete electrical cabinets—downgrade the input switch to boost profit margins.
♦ Monitor the pump’s status and proactively contact customers regarding maintenance and servicing—this not only enhances service quality but also earns customers a positive reputation.
♦ Proactive maintenance services, bypassing third-party service providers and capturing post-maintenance market profits, ensuring the quality of customer repairs.
