Economical Variable Frequency Drive for PCP
Cost effective VFD
Induction motor control
PVR Eco series VFD is designed only for induction motor control. PCP control and protection features are loaded in the drive module. The main functions include backspin control, sensorless control, regenerative energy handling, etc.
For top drive PCP application
PVR Eco VFD is used for top drive PCP pumps. The VFD can drive single motor or double motors ( high horsepower use e.g. 100HP, 150HP). Thermal relays are standard for individual protection for two electric motors.
