The PFV series is the latest programmable AC power source with four-quadrant regenerative function to return energy back to the grid. With power level up to 200kVA, Preen’s PFV series provides an output voltage range of 0~300V and output frequency of 45~65Hz. Users can select communication interfaces of standard RS-485 and RS-232 and optional GPIB, LAN, and USB. The PFV series also has programming sequence functions of STEP and GRADUAL modes, three-phase independent control, phase angle control, disturbance function and regenerative function.
Applications: Testing on motor, compressor, vehicle to grid (V2G), generator and others that require energy feedback
- Regenerative function can sink the energy from load and return to the grid
- Three-phase independent control to set voltage of each phase
- Phase angle control to set angle between each phase
- Soft start function to reduce inrush current from motor type UUT
- Programming Sequence Function: STEP and GRADUAL modes allow users to easily set sequences of start/ end voltage, frequency and run time for testing purposes
- Touch screen display for easy operation
- Comprehensive protection includes over voltage, over current, over load, input under voltage and over temperature with over 20 corresponding error codes and event log for easier trouble shooting
- Standard RS232 and RS485 interfaces and optional GPIB, USB and LAN interfaces available
- Latest patented power module with high power density and swappable design for better reliability and serviceability
