MAD COMPONENTS AMPX ESC 200A(12-24S) BEC：No PWM Input Signal Voltage：3.3V/5V(compatible) Online Update：not available Throttle Loss Protection：available Phase Short Circuit Protection：available Size(L*W*H)：143.0*72.2*41.2mm Power Line：8AWG Continuous Current：200A (under good cooling conditions) Instant Current：300A (under good cooling conditions) Throttle Pulse Width：default 1050us-1940us, throttle adjustment is available. Voltage Protection：available Temperature Protection：available Speed Signal Output：available Weight(without lines)：580g Working Environmental Temperature：-20~65 Battery Section：12~24S Recommended Battery：24S Compatible Signal Frequency：50-500Hz Current Protection：available Stall Protection：available Error Signal Output: available Protection Grade：IP67 (sealing with resin) Motor Line：8AWG Over Current Protection Once checking current is more than 300A and lasts 3 seconds, ESC will shut off power output, and will resume normal after making throttle zero. Short Circuit Protection Once checking instant current is more than 600A, ESC will power off, and will rework after trouble shooting and powering again. Stalling Protection Motor stall will trigger stalling protection. ESC will resume after making throttle zero and powering again. Voltage Protection Once checking voltage is less than 40V or more than 105V, ESC will alarm and will not start up motor. But it will be out of effect during flying. Temperature Protection When checking temperature is higher than 110 centigrade degree, ESC will output error signal. Once temperature exceeding 140 centigrade degree, ESC will shut off and will resume normal after making throttle zero. Throttle Loss Protection As checking throttle signal loss over 0.3 seconds, ESC will shut off and will rework after throttle signal recovery. Start Protection When motor is not started up after adding throttle for 10 seconds, ESC will shut off and will resume normal after making throttle zero.
