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
