Quanzhou Ausenist Technology Co., Ltd 
Product Description
Ausenist high performance IP54 smart AU620 water pump drive.AU620 drive is a single phase and three phase variable frequency drive that is designed specially to manage water pump's performance to match a wide range of water supply system conditions and requirments.
AU620 drive allows your pump to work more efficiently,safely and smartly, reduce a large amount of energy consumption and prolong the lifetime of your pumps.
AU620 drive is made of high quality components and materials and adopts the latest microprocessor technology
Product features:
1,Pump motor protection for phase loss, overload, overvoltage, undervoltage, etc.
2,Double main pumps online, backpack installation
3,Automatic restart for incoming calls and water
4,Intelligent anti-freeze and anti-rust protection
5,Water shortage, burst pipe automatic shutdown
6,Compatible with permanent magnet synchronous and asynchronous, one machine with two uses (the first in the industry)
The host detects the pressure of the pipe network and sends it to the auxiliary machine, while automatically controlling the auxiliary machine operation stop and PID status according to the pressure condition.
The host machine detects the status of the auxiliary machine in real time and when the host machine fails, the standby host machine automatically becomes the host machine and when the auxiliary machine fails, it automatically skips the auxiliary machine and starts the next auxiliary machine. Ensure that the pump set can achieve automatic switching of the main and auxiliary.
The main and auxiliary engines can be run alternately at regular intervals and in sequence to achieve even use of the pumps and extend their life.
Industry leading dual main pump main auxiliary multi-pump system

| Command Running Channel | Three kinds of channels: 1.Operational panel 2.Control terminal,3.Serial communication port,choose 1 and 2 for master drive and 3 for auxiliaries | |
| Built-in PID | Advanced PID arithmetic to realize closed loop control system | |
| Stall Speed Control | Automatically limit current and voltage at running period to prevent tripping due to frequent overcurrent or overvoltage | |
| Master and Auxiliaries connection | Extensible RS485 design,one drive in the system can be master and controls the other auxiliary drives (4 at most) to work by communication mode, Master drive sends PID feedback information to the auxiliary drives and monitors status of auxiliaries inreal time.Any failure of the auxiliary drives does not affect the others. | |
| Water Shortage Protection | If the drive detects the pipe pressure is lower than the water shortage pressure set value,the system stops working automatically.After set period time,it restarts automatically for specified times.If pressure restores to normal,system works normally,otherwise,system stops automatically in case of idle running of pump and prolongs pump lifetime to the maximum extent. | |
| High Pressure Alarm | When pressure exceeds set pressure,it stops running automatically to avoid damage on pipe network due to high pressure. | |
| Automatic Energy-saving Running | Automatically lower output voltage under light loading to save energy | |
