Single Sewage Pump Controller

Detailed Product Description

Single Sewage Pump Controller Ac380v Input Voltage ,Connection With 0.5-4.5v Level Transmitter ,With One Button Calibration

General Description

Intelligent Three Phase Duplex Sewage Pump Controller AC380V Input Voltage , DOL Start Type , One Button Calibration

L931-s Sewage Pump controller ,is a smart and intelligent three phase fully automatic pump controller with built-in water level control .

It is very useful in water and waste water applications,The unit features an advanced microprocessor controller bonded to the PCB boards within the enclosure. The unit will support two Three phase 380 VAC pumps rated up to 15KW.

The controller unit is housed in a tough IP54 rated plastic enclosure with a LCD displaying front so that various status indicators may be viewed. This allows routine pump checks and maintenance to be carried out without the presence of an electrician. (Installation and maintenance of all electrical components will still require the presence of a qualified electrical contractor.)
