DESCRIPTIONS AND FEATURES
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
• Protection features
– Dry run conditions – using intelligent load monitoring
(see Page 7)
– Bound pump – with auto-reversing torque
– High voltage / lightning surge
– Low line voltage
– Short circuit
