variable frequency drive, CHV160A series Special Inverter for Multi-pumps Water Supply

CHV160A(variable frequency drive)adopts the advanced control theory to adjust speed and switchover of pumps automatically.

3AC 380V±15% 5.5~350kW

 

Instruction

The CHV160A Series is a strong inverter designed for heating, ventilation, air conditioning and water supply. It is applicable for supporting fans and water pumps. This inverter employs advanced control theory to automatically adjust pump speed and switchover according to the pressure in the pipe network, so as to provide constant pressure.

Technical Features

1.CHV160A Series Inverter = PLC +PID regulator + inverter;

2.Supporting multiple water supply modes, including fixed variable frequency pumps (can define up to one fixed ariable pump + nine general pumps) and circulating variable frequency pumps (can define up to four circulating variable pumps + two general pumps);

3.Optimized water supply PID regulator can shift between two sets of PID parameters;

4.Flexible control logic for adding or removing pumps;

5.Flexible dormant pump controls;

6.Timed rotation control can effectively prevent pump corrosion;

7.Eight timeslots for water supply and up to sixteen pressure settings;

8.Built-in inlet and sewage pool water-level detection and logic control functions;

9.Manual soft-start debugging and manual cyclical debugging allow for easy maintenance;

10.Pipe network pressure monitoring and warning systems;

11.Excellent protection against water pump grounding and phase deficits;

12.Built-in standard Modbus communication protocol.

 

Application

1.Water for daily use, heating, and fire prevention for skyscrapers, housing development, offices, and businesses.

2.Central air-conditioning systems and dual water supply systems.

3.Water for use in mining and industrial production and circulation cooling water and water supplies for industrial boilers.

4.Oilfield oil pipelines, oil depots, oil pump stations, oil ports, and other constant pressure oil supply systems.

5.Water treatment plants and feed water booster pump stations.

6.Waste water treatment.

7.Irrigation systems for large plazas, parks, and farms.

8.Fan and pump OEM.

Optional accessory

Water-supply extension card.
