frequency conversion contron starting three phase imbalance short circuit water shotage protection dry-run protection

The scope of Application

ATQD series frequency conversion control cabinet is designed by adopting advanced technology. With built-in PIC controller, it can automatically adjust the pump’s rotating speed and switching according to pipeline pressure, liquid level and fow rate. This powerful cabinet could protects the whole set from shot cricuit, phase failure, overload, three phase imbalance, water shortage,ect

The Advantages of Equipment

1.  It is suitable for regular pump, sewage pump, realizing the control of as many as 7 pumps.

2.  Control module integrates internally with clock chip. Also, the frequency power is equipped with it, which is more convenient to control regularly.

3.  You can set the pressure during the eight different time period to satisfy the needs of actual water supply.

4.  Save energy in dormancy status; regular operating rotation; low flow rate automatic stop.

5.  Preventing secondary pollution by examining and controlling the inlet liquid level.

6.  Protect functions of pipeline overpressure/subpressure, liquid level, flow rate; and automatically record and switch the faulted pumps

7.  Supply the standard RS232 and RS485 serial communication interface, which adopts ModBus international standard communication protocol.
