The Professional-100A supports 2-6S Li-poly battery pack or 5-18 cells NiCd/NiMH battery pack. It is a good choice for big RC aircraft and helicopter models.
It come with a custom-built heat sink for Professional-100A, it has a perfect heat sinking effect so the whole ESC works more reliable.
There are 4 earholes on the base board, so it is very easy to install the ESC firmly with screws.
■ 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 featurers:
●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: 2.5V/2.75V/3.0V. For example: 10 Cell Li-Poly, when medium cutoff voltage is set, the cutoff voltage is: 2.75*10=27.5V.
■ 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.
● Military Standard Capacitor with extreme low resistance used on voltage input section, this will increase the ability of prevention of unwanted RF Noise/ Interference during flying.
● Extreme low resistance PCB used on power output section, the thickness of copper sheet is more than 0.7mm.So the whole ESC has super current endurance capability.
● Compatible with Program Card for HiModel HW/Balancer/Economic/Professional Series ESCs.
● Output: Continues 100A, Burst 120A up to 10 Secs.
