As the VFD manufacturer in china, V&T E5-H series is a high performance universal vector control inverter with superior performance-price ratio and powerful control functions. It is widely used in various drive and speed regulation in the fields of machine tools, food, paper making, metallurgy, chemical industry, wire and cable, power, textile and transmission.

E5-PA series is a new constant pressure water supply inverter launched by V&T. E5-PA inverter, combined with the multi-pump control expansion card, can realize the multi-pump constant pressure water supply in turn with circulating; Built-in PID control--the current water pressure is detected by the pressure sensor, and according to the change of water pressure, 4 pumps are automatically switched to water supply at constant pressure under same power; At the same time, it can realize overpressure alarm, underpressure alarm, multi-time water supply at constant pressure, water supply at pressure constant with designated pressure and designated date, sleep control, change pump on time etc.
