Preen AFV Programmable AC Power Source Series

The Preen AFV series are programmable AC power supplies for grid simulation up to 2000kVA. With advanced SPWM technology and direct digital frequency synthesis (DDS) waveform technology, these power supplies have stable output frequency and excellent continuity. AFV series power supplies provide continuous, pure and stable sinusoidal voltage. They can be locally touch-screen adjusted or remote-controlled through a PC to provide complete output voltage and frequency variations.  STEP and GRADUAL features are ideal for R&D and compliance testing. The internal electronics can quickly detect over-current, overload, over-voltage and output short circuit, and automatically protects and cuts off the output, sounding an alarm. The integrated laminated busbar technology and modular configuration in the power supply inverter unit ensure reliability and stability.
