220v constant voltage automatic water pump digital controller

 220v constant voltage automatic water pump digital controller

1.1 Main functional features

1.1.1 Include 3 sets of main pumps & a set of small pump, it has multiple controlling mode and meets all kinds of complex requests of water supply.

1.1.2 It has timing change pump function so that each pump’s working time is equal, and extend pump’s working life.

1.1.3 It not only has 8 periods of pressure control but arbitrary pressure setting and time & power on-off function in each period as well.

1.1.4 Sleep function and auxiliary small pump function, save enery and reduce the cost, extend machine’s life.

1.1.5 It has negative and positive feedback function, it can be used in water supply, but also can be used in pump water and keep water level.

1.1.6 It has over-pressure, low water-level, sensor breaks, VFD fault alarm functions etc.

1.1.7 Feedback can connect to passive remote pressure gauge, active voltage and current type of transmitter.

1.1.8 Feedback components’ power of 0-24V can be modified, strong universality.

1.1.9 Feedback signals can be selected, it is more convenient to connect with outer.

1.1.10 Standard of 0-10V output voltage, or it can be change to any voltage values, more flexible.

1.1.12 Relay fault output function is optional.

1.1.13 Strong adaptability, it is suitable to all kinds of different brand inverters.

1.1.14 Digital signal is adopted photoelectric isolation.

1.1.15 With complete key function.
