The DYS Quanum 30A ESC is a programmable multi-copter brushless speed controller with a 5V/3A BEC, sold as the original. The page says the power input uses extremely low output resistance, which greatly improves power stability and protects the battery.
The specification list gives a blue colour, a running current of 30A continuous with a 40A burst for up to 10 seconds and an input of DC 6-16.8V (2-4S). Maximum supported motor speed is 210,000 RPM (2 poles), 70,000 RPM (6 poles) and 35,000 RPM (12 poles). The page showed it in stock at Rs 725 (SKU RS7319).
30A continuous, 40A burst: burst up to 10 seconds.
5V/3A BEC: as named in the title.
DC 6-16.8V (2-4S): input voltage.
Extremely low output resistance: for power stability and battery protection.
Startup safety function: the motor does not start at power-on.
Programmable: as named in the title.
An electronic speed controller (ESC) converts the throttle signal from the flight controller into the three-phase power that a brushless motor needs. It switches battery current through MOSFETs at high speed, so the motor turns at the speed that the pilot or autopilot asks for. The continuous current rating shows how much current the ESC can carry all the time, and the burst rating shows what it can survive for a few seconds.
Match the ESC to the rest of the power system. The battery cell count must fall inside the listed range, the continuous current must be higher than what your motor and propeller draw at full throttle, and the signal protocol (for example PWM, Oneshot, Multishot or DShot) must be supported by your flight controller. An ESC marked OPTO has no built-in BEC, so the receiver and flight controller need power from another source. An ESC with a BEC can supply a regulated voltage, usually 5V, to small electronics.
Install and test carefully. Solder joints must be clean and strong, the motor wires should be kept short and tidy, and the ESC needs airflow because current makes heat. Calibrate the throttle range if the ESC needs it, check the motor direction with the propellers removed, and never connect a battery with the propellers fitted while you are working on the wiring. Use a battery with a cell count and connector that suit the ESC, and check for a heat problem after a short test hover.
