Hobbywing Pentium-40A ESC

-Safety Arming Feature: Regardless the Throttle Stick position, the motor will not spin after battery connected. This will prevent any injury happened. 
- Throttle Calibration: Throttle range can be configured to provide best throttling linearity, fully compatible with all market available transmitters.
-Programmable Items:
●Brake Settings：brake enabled / brake disabled, default is brake disabled 
●Battery Type：Li-xx(Li-ion or Li-poly) / Ni-xx(NiMh or Nicd)，default is Li-xx.
●Low Voltage Protection Mode(Cutoff Mode) ：power reducing / power cutoff, default is power reducing.
●Low Voltage Protection Threshold(Cutoff Threshold) ：low / medium / high, default is medium cutoff voltage.

-For Li-xx battery，number of battery cells are judged automatically，low / medium / high cutoff voltage for each cell are: 2.6V/2.85V/3.1V. For example: 3 Cells Li-Poly, when medium cutoff voltage is set, the cutoff voltage is: 2.85*3=8.55V.
-For Ni-xx battery, low / medium / high cutoff voltages are 0%(ie. never cut off )/45%/60% of the startup voltage. For example: a 10 cells NiMH battery pack, fully charged voltage is 1.44*10=14.4V, when medium cutoff voltage is set, the cutoff voltage is : 14.4*45%=6.5V.
●Startup mode: normal / soft / super-soft, default is normal startup.
●Timing: low / medium / high, default is medium timing. In normal cases, low timing can be used for most motors. But for high efficiency, we recommend the Low timing for 2 poles motor and Medium timing for 6 poles and above. For higher speed, High timing could be used.
-Full Protection Features: Low-voltage cutoff protection / over-heat protection / throttle signal lost protection.

Advangages
-Military Standard Capacitor with extremely low resistance used on voltage input section, this will increase the ability of prevention of unwanted RF Noise/ Interference during flying. 
-Seperate PCB for control circuit and MOSFET circuit: adiabatic air gap between control circuit PCB and MOSFET circuit PCB reduces the heat exchange form MOSFET to control circuit, so the ESC works more reliable.
-Extreme low resistance, super current endurance.
-Microprocessor and BEC use separate voltage regulator IC, with good anti-jamming capability.
-Compatible with Hobbywing's Program Card .
-Own complete intellectual property rights.
