YS820 & YS620 Series: The Ultimate Choice for Energy-Saving & Multi-Pump Water Systems
Why global pump manufacturers are choosing Ausenist VFDs
Traditional fixed-speed water pumps waste enormous energy when demand fluctuates. Ausenist YS820 and YS620 series smart pump drives automatically adjust motor speed in real time, delivering 30–50% energy savings while maintaining stable pressure — proven in thousands of real installations worldwide.
Core Advantages That Make Your Pumps Stand Out
- Built-in advanced PID for precise constant pressure control
- Water shortage protection + automatic restart (up to hundreds of times)
- Master + up to 4 auxiliary pumps via RS485 communication (YS620 supports up to 4 auxiliaries)
- Automatic pump alternation for even wear and longer service life
- Comprehensive motor protection: phase loss, overload, overvoltage, undervoltage
- Compatible with voltage/current pressure sensors (default 10kg/1MPa range)
- Quick parameter setting: sensor type/range adjustable in seconds
- Compact design, easy integration into 0.75–7.5kW pumps
AU620 IP54 VFD: Direct-Mount, Dustproof & Waterproof – Built for Harsh Environments
The first choice for outdoor & industrial water pump applications
With full IP54 protection, the Ausenist AU620 intelligent pump VFD can be directly mounted on pump motor junction boxes — no extra enclosure needed. This dramatically reduces installation costs and time while providing superior dustproof and waterproof performance for farms, mining, desalination, and municipal systems.
Industry-First Features That Set AU620 Apart
- One VFD controls both permanent magnet synchronous (PMSM) and asynchronous motors – first in the industry
- Double main pumps online + backpack installation for true redundancy
- Intelligent anti-freeze & anti-rust protection (automatic periodic running)
- Water shortage & burst pipe automatic shutdown + protection
- Automatic restart after power/water recovery
- Host monitors up to 4 auxiliary VFDs via RS485, with automatic failover
- Low noise, superior performance, easy operation
