THE IRZ-400 SERIES VFDs control, protect, verify parameters, and regulate rotation frequency of SRP or PCP systems arranged with surface three-phase induction or permanent magnet motors.
Main feature of the smart VFD is that user can build up calculated dynamometer chart without dynamograph or other sensor mounted on moving parts of the pump system.
Using VFD, customer is able to CONSTANTLY MONITORING operation of the pumping equipment, as well as pump fill factor and well production rate.
Adjustable graphic presentation of any parameter on the drive’s display or a PC
Load curve drawing without a dynamograph
