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
•
