demand, the controller always slowly increases the motor speed while gradually increasing
the motor voltage. Compared with the traditional water supply system, the motor
temperature and starting current of the solar water pump system are lower. Since the
controller has a soft start function, there is no damage to the motor.
■
Overheat Monitoring
The PDS51 solar pump controller can also run at full power when the ambient
temperature reaches 45°C. At temperatures above 45°C, the controller reduces the carrier

and maintains operation as much as possible.

The PDS51 solar pump controller can be connected to 2 water level detection switches
to remotely control the operation of the water pump. The water level switch is optional for
the PDS51 solar water pump controller, but not mandatory.
