ALPHA6600 series AC drive for constant pressure water supply system fully utilizes the hardware advantages of ALPHA6000. It has high performance andcan drive 4 sets motors (drive 2 motors in circular running) without watercontrol card/controller, which provides excellent drive and control solution inwater supply and HVAC industry.
Voltage fluctuation range is ±20%.
Composed of the AC drive and the PID regulator.
Comprehensive watersupply solution; flexible configuration of general pump, fire pump, and pump with sleep mode; easy to realize automation of water supply pump system;circular pump mode: drive 2 motors; fixed pump mode: drive 4 motors
Keep constant pressure under any flow condition
Simple setup anddiagnosing on pumps
Make pumps runalternatively based on its working time to avoid the pump’s unbalanced wear
Turn on/off subsidiary pumps according to the technical specifications; control the variable pump to ensure continuous flow changing
When one single variable-speed pump fails to meet requirement of complete flow range, the system adopts one variable-speed pump and multiple fixed speed pumps (Max. 4units) with built-in PID regulating the pumps and pressure sensor giving feedback
The AC drive is ideal for use in the non-tower water feeder, non-negative pressure water supply system, the residential water supply system, as well as the urban central heating and water supply system.
