D1 INTELLIGENT CONTROL BOX FOR WATER PUMP

D1 Intelligent Water Pump Controller

(Three-phase LCD panel, 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

Main Technical Parameters

Rated working voltage: AC380V±10%/50Hz

Matching motor power: 0.75kw-22kw

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

Timing start time: adjustment range 00-48 hours

Customized shutdown time: adjustment range 00-480 minutes

Over/under voltage protection range: 304v-456v (≤3 seconds trip) upper and lower limits are adjustable

Over/under current action time: 0.1 second-3 minutes (inverse time limit characteristic)

Phase loss action time: <2 seconds

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

Independent key setting of overload and no-load protection current parameters (adjustable no-load delay start)

After the over/under voltage is protected, it will automatically start after the voltage returns to normal

One-key setting of overload/idling current protection

Manual/automatic start and stop, timing start and stop

Liquid level control, pressure control, switch direct conversion

Automatically start the water pump after a power failure

The upper and lower limit pointer contact status indication of electric contact pressure gauge

No-load restart: adjustment range 0-999 minutes
