The Basic ESC 500 is a high-power electronic speed controller (ESC) for three-phase brushless motor like Blue Robotics’ thrusters and motors. It has a 50A current rating suitable for both the T200 and T500 Thrusters and is suited to operate in poorly cooled installations, such as in an ROV enclosure.
