JETI Model JSP-77-O SPIN Pro Opto 77 Brushless 77A Electronic Speed Controller
JETI Model JSP-77-O SPIN Pro Opto 77 Brushless 77A Electronic Speed Controller is an ESC. The SPIN Pro line offers, in comparison with the predecessors, increased adjustment possibilities, such as automatic motor timing, shut-off voltage adjustments practicable directly in volts, tuning of start-up properties for different motor types, as well as new possibilities of mode activation for setting up autorotation of helicopters.
Opto controllers have galvanically separated input (the receiver signal) from power accumulators, therefore it’s necessary to use independent power supply for the receiver and servos (4-5 NiXX or 2-3 LiXX with linear voltage regulator, such as MAX BEC).
SPIN opto controllers are provided with two JR connectors. Connector on the longer three-line cable with black ending is to be linked to the receiver. Connector on the shorter three-line cable with red ending is intended for communication with JETIBOX; for programming or data reading connect it into slot marked imp. – on JETIBOX.
