WATER SUPPLY CONTROL CARD
One inverter can control up to seven pumps to make the constant-pression water supply.
- The model of “water supply card” is CHV00GS. With water supply card, CHV series inverters
can provide constant-pressure water supply. This also can implement the settings and automatic
switching logic of variable frequency pumps, power frequency pumps, dormant pumps and dredge
pumps. Meanwhile it can implement such functions as multi-step water supply, dormant control, dredge
control, periodic pump change and faulty variable frequency judgment.
