VFD-W Freuqency inverter
This series inverter is designed for water supply at constant pressure. It can switch to as many as 7 pumps, each of them enjoying free manual or automatic control with no influence on the other pumps working. The total number of pumps to be switched to can be set from the keypad program, with setting value of 2-4 for multi-pump circulation frequency conversion. Instantaneous impact on value while being switched between pumps can be avoided through special processing. All the individual pumps can operate under even load through logic arrangement in case a certain pump may risk erosion due to long idling.
