Empowering Modern Water Supply:
The Breakthrough of the AU620 Intelligent Pump Drive
Revolutionizing efficiency, reliability, and smart control in water management systems.
In the evolving landscape of industrial automation, Quanzhou Ausenist Technology Co., Ltd has introduced a game-changing solution for water management: the AU620 Intelligent Water Pump Drive.
Designed to enhance the performance of three-phase AC380V water pumps, this advanced variable frequency drive (VFD) is redefining efficiency across residential, educational, and industrial sectors.
The End of Bulky Infrastructure
Traditional constant pressure systems relied on large pressure tanks and mechanical switches, often resulting in frequent pressure cycling and high maintenance demands.
The AU620 Drive eliminates these outdated requirements. Its intelligent design continuously monitors pipe pressure and automatically adjusts water inflow to maintain perfectly constant pressure at all times.
Smart Multi-Pump Integration
One of the AU620’s most powerful features is its Multi-Pump Control system. With an extensible RS485 communication design, it supports a “Two Masters and Max. 4 Auxiliaries” configuration.
In this setup:
The Master drive detects pipe network pressure and sends real-time PID feedback to auxiliary drives.
An alternating run function (default 8-hour rotations) balances wear and tear across all pumps, extending equipment lifespan.
“Fault Shift” logic ensures reliability: if the Master fails, a Standby Master takes over automatically; if an auxiliary fails, the system skips it and activates the next available pump.
Unmatched Protection and Durability
Engineered for harsh environments, the AU620 features an IP54 protection level — dustproof and waterproof — and supports backpack installation directly on pump motor junction boxes.
Comprehensive digital protections include:
Dry run and water shortage protection
High/low voltage and phase failure protection
Intelligent anti-freeze and anti-rust functions
Burst pipe automatic shutdown
Industry-Leading Compatibility and Efficiency
The AU620 stands out with compatibility for both permanent magnet synchronous and asynchronous motors — offering true “one machine with two uses” flexibility for system integrators.
By running the pump only at the precise speed needed to maintain set pressure, it dramatically reduces energy consumption and provides a soft start to minimize motor inrush current.
