D2 INTELLIGENT CONTROL BOX FOR WATER PUMP

D2 Intelligent Water Pump Controller

(Three-phase LCD, one control two 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 probeThis machine has the functions of double pump rotation, double pump start at the same time, automatic fault conversion, fault alarm, etc， so that the pump is truly intelligent. Humanized management.

Main Technical Parameters

Rated working voltage: AC380V±10%/50Hz

Matching motor power: 0.75kw-15kw

Host static power consumption: <3kw

Three levels of water level display, in order: low, middle, high

Maximum control distance: no strong electric field, magnetic field and interference environment ≤ 2000 meters
