[PSUBS-MAILIST] Kelly controllers

Thu May 19 10:59:07 EDT 2016

Scott.  I would try one of the MC 101 motor controllers for each vertical
thruster.  They should work well for this application.  The motor
controller has a soft start which should solve the fuse blowing.  You don't
need a reversing contactor with these controllers.  When the pot is near
the center of its taper (2.5vdc) the motor to the thruster (10AWG) are also
connected with 1/4" spade connectors.
