ALPHA6600 Series AC Drive for Constant Pressure Water Supply System

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.

Technical Characteristics

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

Applications

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.
