LBP series frequency control cabinet

Features:

1. Energy efficient

The system can set pressure on demand, the system will automatically adjust the pump speed and pump operating units according to the set pressure, the equipment running at peak energy efficient.

2. The water pressure is stable

Closed-loop control system can automatically adjust the system pressure and set pressure difference, the system pressure is kept constant.

3. Easy operation, simple

Drive or drive system is composed of intelligent controller plus automatic control, easy to operate.

4. The extension of motors, pumps life

The pumps are all soft-start eliminates inrush current at start, prolong the service life of the equipment; each pump cycle soft start, so that each pump will not be long without rusting or frequent use and wear.

5. The perfect protection function

Short circuit, overcurrent, overvoltage, overheating, overload and other protection, water pumps run if fault, automatically stop working and alarm output; the system has a self-test, fault diagnosis, fault memory, fault display, automatic start standby pump and other functions .

6. Low Flow subsidiary small pump auto-run feature

It can be connected with a subsidiary small pump, allowing the system to run at night or in other low flow conditions, automatically turn off the main pump, turn on the subsidiary small pump, in order to avoid waste due to open high-power pump caused.

7. frequency regulation, effectively avoid the "water hammer" phenomenon.

8. Programming and setting the drive and controller convenient and simple, easy to grasp.

9. equipped with a manual switch control, you can ensure the safety of the equipment for continuous operation.

10. Communication and computer serial port can connect, and computer networking direct control.
