Frequency conversion control cabinet product features

1. Use international famous brand inverters, programmable controllers and famous brand low-voltage electrical appliances;

2. Digital PID adjustment, keyboard operation, digital display, fully automatic operation and unattended operation;

3. The circuit design is concise and clear, making it easy for fault analysis and maintenance;

4. Frequency conversion adjustment effectively avoids the "water hammer" phenomenon.

5. The programming and setting of the inverter and controller are convenient and easy to master.

6. Excellent performance, flexible control method, strong anti-interference ability, stable and reliable operation;

7. The pipe network pressure is constant without impact, automatic/manual switching control;

8. The communication serial port can be connected to the computer to realize direct control of the computer network.

9. The water supply pressure is stable, and the system implements closed-loop control, which can automatically adjust the difference between the system pressure and the set pressure to keep the system pressure constant.

10. In the automatic state, the water pump motor realizes soft start. No impact on the power grid and pipeline network, greatly extending the service life of water pumps, motors, pipeline systems, and electrical control systems;

11. Manual and automatic control function settings can ensure the safe and continuous operation of the equipment;

12. The control is programmed and a variety of control methods can be implemented according to user requirements. Such as: timed switch system, fire linkage, automatic shutdown and sleep with no flow and zero flow, centralized management of the host computer, etc.;

13. Multiple pumps can run alternately in cycles, balancing the average working time of each pump to extend the service life of the water pump, thereby avoiding corrosion of the standby pump due to long-term non-operation, and ensuring that the water pump can be put into operation smoothly when a fire occurs;

14. The basic control functions are powerful and optional additional functions are abundant. Such as: timer switch system, automatic soft change of water pump. Automatic shutdown and sleep, remote control, and local control cabinet when using low-flow or zero-flow water.

15. Complete protection functions, with various protections such as short circuit, overcurrent, overvoltage, overheating, overload, etc. If there is a fault in the operation of the water pump, it will automatically stop working and alarm output; the system has self-test, fault judgment, fault memory, and fault display. , automatically start the backup pump and other functions.

16. Use PLC programmable controller to implement human-machine interface for pump units and other equipment, supplemented by computer technology for intelligent control.
