Chapter 2 General Information
The PDS33 solar pump controller is a variable speed motor drive designed to run
any IEC three-phase asynchronous motors. The PDS33 solar pumping system
provides water to remote locations by converting high voltage, direct current from
a solar array into alternating current to run a standard three-phase asynchronous
motor. When solar power is not available, the controller can be switched manually
to an alternate single-phase or three-phase AC input such as a generator or inverter
from battery, if available. The controller provides fault detection, motor soft start,
and speed control. The PDS33 solar pump controller is designed to provide these
features with the plug and play ease of installation.
The PDS33 solar pump controller is designed with the high standard of reliability
expected of products. The controller attempts to drive the pump and motor to
deliver water even under adverse conditions, reducing output as necessary to
protect the system components from damage, and only shutting down in extreme
cases. Full operation is restored automatically whenever abnormal conditions
subside.
2.1 Inspection
Before starting
，
inspect the PDS33 solar pump controller unit. Verify that the part
number is correct and that no damage has occurred during transit.
NOTE:
PDS33 solar pump controller is one component of a PDS33 solar pumping
system which has other two optional components, solar array and AC pump with
motor.
2.2 Descriptions and Features
The PDS33 solar pump controller is based on a standard PDS33 platform
controlling a standard three-phase asynchronous motor driving a pump powered by
