Chapter 2 General Information
The PDS23 solar pump controller is a variable speed motor drive designed to run
any IEC three-phase asynchronous motor. The PDS23 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 PDS23 solar pump controller is designed to provide these
features with the plug and play ease of installation.
The PDS23 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 you begin, receive and inspect the PDS23 solar pump controller unit. Verify
that the part number is correct and that no damage has occurred during transit.
NOTE:
PDS23 solar pump controller is one component of a PDS23 solar pumping
system which has other two optional components, solar array and AC pump with
motor.
2.2 Descriptions and Features
The PDS23 solar pump controller is based on a standard PDS23 platform controlling
a standard three-phase asynchronous motor driving a pump powered by a solar array
or an optional AC generator backup.
