Product Description

Pump Inverter for pressure control


B603D/B2 series intelligent constant pressure water supply controller is suitable for full-automatic operation, with characteristics of high quality, multi-functional, low noise and strong commonality etc.
There are no special demands for peripherals, it mainly use normal components, for example: Water detection use transducer, transmitter (include water level transmitter, temperature transmitter, etc. ) or inductive remote transmission pressure gauge, with output of 4~20mA, 0~5VDC and 0~10 VDC standard signal.
Power range:

I B603A series Intelligent constant pressure pump controller
Single phase 220V input, 3 phase 220V output: 1HP-7HP(0.75KW-2.2KW)
Three phase 220V input, 3 phase 220V output: 4HP-75HP(3.7KW-55KW)
Three phase 380V input, 3 phase 380V output: 1HP-470HP(0.75KW-350KW)

II B603B series Intelligent constant pressure pump controller(water proof)
Single phase 220V input, 3 phase 220V output: 1HP-3HP(0.75KW-2.2KW)
Three phase 380V input, 3 phase 380V output: 1HP-3HP(0.75KW-2.2KW)

Function characteristics:

Multi-pump control: Can realize 1 master and max. 5 auxiliaries combine work

Sleep function: Sleep down when have no water consumption, to earn a better energy saving

Freeze-proofing function: Suitable to low temperature area, prevent pump from freezing

Anti-clogging function: Take precaution against pipe clogging and clean the pipe dirt

Power on restart: Running automatically when power on

Master fault shift automatically: Keep on working when the master break down

Alternate running: Balance every pump's running time, prolong service life of the whole unit machine

Day-part function: 3 independent day-part control, up to 7 day-part achieved when define separated

Two running mode: Synchronous control mode, master-slave control mode

Terminal control mode: Terminal run/stop, manual/auto control, electronic contact gauge control

Various of water supply fault alarm function: High-pressure, low-pressure, low-level, transducer error etc.

As many as 22 kinds of fault protection function: Over-current, over-voltage, low-voltage, phase-failure, over-load etc.
