Commander
Speed Controller System
Instructions
The Commander ® Pro Variable Speed Controller is a
dependable water system Variable Frequency Drive (VFD)
that uses custom programming to enhance the performance
of submersible pumps . When applied correctly to three phase
motor driven pumps, the drive eliminates pressure cycling
associated with conventional pressure switch controlled water
pumping systems and provides a constant output pressure .
Key features of the drive controller include:
•
Can use either a pressure switch (no snap action) or
a 4-20mA transducer as the pressure control . At initial
power up, the controller detects whether a switch or
transducer is connected and automatically sets the
control choice .
•
Constant water pressure with a wide range of settings
(30-80 psi) (Note: The maximum obtainable system
pressure is limited by the performance of the pump
installed)
•
Smaller pressure tank can be used
•
Fits the pump to the application – pump speed is
controlled to provide the optimum performance without
overloading the motor
•
No in-rush (power-on transient) current
•
Low motor start-up current (soft-starting)
•
Active Power Factor Correction minimizes input RMS
current

Switch two of the three wires leading from the controller to the high as expected . 3-phase motor . Pump capacity cannot supply the demand . Use pump with higher flow rating (if head requirement is still satisfied) .
