The PDS33 Solar Controller is a variable speed motor driver designed for any IEC-compliant three-phase asynchronous motor. The PDS33 solar pump system converts the high-voltage direct current of the solar array into alternating current, driving a standard three-phase asynchronous motor to supply water to remote areas. When the solar energy is insufficient, the controller can manually switch to a spare single-phase or three-phase AC power source, such as a generator. The controller also provides fault detection, motor soft start and speed control function. The PDS33 solar pump controller has specially designed plug-and-play function and is easy to install.
