Water Supply Controller, frequency inverter (AC drive)
water supply card
This constant pressure water supply card, is applied to control the constant pressure water supply pumps. With this Water Supply Control Card, the multiple pumps water supply system will be controlled effectively.
When several pumps supply water meanwhile, because of the different time(daytime and night), different season(winter and summer), the variation of the water flow is great. To save energy consumed and protect the equipment, please run pumps as many as you need and stop pumps as many as you do not need.
Frequency inverter (variable speed drive) will confirm the number of the running pumps according to the requirement of the pressure close loop control.
This water supply card is optional part for our frequency inverters.
