D3 INTELLIGENT CONTROL BOX FOR WATER PUMP

D3 Intelligent Water Pump Controller

(Three-phase liquid crystal pressure plate, one control one pump)

Scope of application: control and protection of water supply, underground sewage discharge and deep well pumping of high-rise buildings

Dimensions: 344*233*131mm

Product Description

This machine adopts the original imported microcomputer single-chip technology, which has the advantages of powerful function and simple and convenient installation. The unique non-contact induction technology can realize the shutdown protection of the pump when the pump is running dry without water without installing the probe, so that the pump is truly intelligent. Humanized management.

Main Function

Pressure control characteristics: three-wire electric contact pressure gauge/two-wire pressure switch

Liquid level control characteristics: electrode probe or buoyancy switch detection

Display characteristics: voltage display, current display, upper/lower pool water level display

Fault status: fault cause display, fault sound and light alarm

Control mode: manual/automatic one-key conversion

Upper pool water supply control, lower pool drainage control, constant pressure water supply control

Locked-rotor protection, water shortage protection

Phase loss protection, short circuit protection, over/under voltage protection

Manual/automatic start and stop, timing start and stop, the water pump will be automatically started after power failure

Three control modes for drainage/water supply level control and pressure control

Overload/no-load protection, independent setting of current parameters

Electric contact/remote pressure gauge/pressure transmitter/pressure switch four pressure control modes

Six kinds of control elements can be connected: pressure transmitter, remote pressure gauge, electric contact pressure gauge, pressure switch, float, probe

The upper and lower limits of the pressure sensor are digitally displayed, and the pressure parameters are adjustable on the controller
