3 phase inverter

ALPHA6600 inverter is high performance inverter combined with ALPHA6000's hardware according to the market demand. It can drag max. 4 units motors (2 units for circular running) without water supply card/controller. It provides excellent drive and control solution in water supply and HVAC industry. 

Technical Feature: 

1. Power range: 7.5kW ~ 400kW
2. Wide input voltage range: 304 ~ 456V, voltage fluctuation: ±20%
3. ALPHA6600 special inverter for water supply = PLC + inverter + PID regulator
4. Comprehensive water supply solution, flexible configuration for general pump, fire pump, dormancy pump, easy to achieve water supply automation, circular pump mode: 2 units, fixed pump mode: 4 units
5. Keep constant pressure under any flow
6. Setting & diagnosing the pump simply
7. Switching the pump in turn according to its working time to avoid the pump's unbalanced attrition
8. Turn on/off subsidiary pumps according to the technical specification, control the variable pump to ensure flow changing continuous
9. The system adopts one variable frequency pump and multiple fixed frequency pumps (max. 4 units), and used one PID regulator to control the pumps, provided the system feedback by pressure sensor, while only one variable frequency pump can't meet the flow range completely

Application
Water supply without tower, water supply without negative pressure, water supply in urban resident/ residential area, concentrated water and heat supply in city, Cycle cooling water system, Industrial boiler, Oil transportation pump, Water & sewage treatment
