Hobbywing Pentium-30A Brushless ESC TL2761 Specifications 1.1 Output: Continuous current 30A, short-time current 40A (less than 10 seconds); 1.2 Power input: 5.6V - 16.8V (2-4 cells lithium battery or 5-12 cells NiMH / NiCd battery pack); 1.3BEC output: linear regulator mode, 2A 1.4 Maximum Speed: 2-pole motor 210000 rev / min, 6-pole motor 70000 rev / min, 12-pole motor 35000 rev / min; 1.5 Size: 45mm * 24mm * 11mm 1.6 Weight: 25g 1.7 Accessories: gold-plated motor connectors and heat shrink tubing three pairs (optional); Features 2.1 Safety quan ¦Ä broom? Lt ;/ font> power Regardless the throttle stick position, the motor will not start immediately, to avoid injury; 2.2 Throttle Calibration: Throttle range can adapt to different differences, improve throttle response linearity, with smooth, delicate texture and excellent throttle speed linear; 2.3 Programmable Items: Brake Settings: brake enabled / brake disabled, default is no brakes. Battery Type: Li-xx (lithium battery) / Ni-xx (nickel-cadmium or nickel metal hydride), default is Li-xx (lithium battery). Low Voltage Protection Mode: reduces power on / off output, the default is to reduce power. Low Voltage Protection Threshold: low / medium / high, default is medium cutoff voltage. When setting using a Li-xx battery, then automatically determine the number of pieces of lithium, low / medium / high cutoff voltage for each cell are: 2.6V, 2.85V, 3.1V. When setting using a Ni-xx battery, ESC automatically detected on power battery pack voltage, low / medium / high cutoff voltage when the input voltage is switched to 0%, 45%, 60% (0% means with low voltage protection do) Boot mode: Normal / Soft / Super-Soft startup, the default is normal startup. Normal start for fixed-wing, you can quickly within 0.2 seconds to start the motor Soft start / super soft and starting for helicopters; soft start and super soft and starting relatively low initial speed, full-speed, respectively, from the start to need one second and two seconds, but if the throttle is closed after startup, start again within three seconds when the expressed in normal mode is activated, in order to avoid doing some stunts when flying too slow to react caused due to the crashes. Timing: low / medium / high, default is Middle. Under normal circumstances, low timing can be used for most motors, but for efficiency, the proposed two-pole motor with low into the corner, 6-pole motors in use over into the corner. To improve speed can be set high into the corner into the corner. In a more improved angle setting, it should first be tested on the ground before flight. Restore factory defaults 2.4 Full Protection Features: Undervoltage protection: set by the user through the program; Overvoltage protection: input voltage exceeds 18 volts will not start, automatic protection, also issued a rapid "beep beep" alarm sound; Overheat protection: Built-in temperature sensing circuit, MOS tube temperature is too high, the ESC automatically turn off; Remote control signal loss protection: remote control signal is lost one second after power down, and then have two seconds to turn off without the remote control signal output; 3 Process characteristics 3.1 ultra-low power input impedance using military large-capacity electrolytic capacitor, which greatly improve anti-jamming capability; 3.2 Output power MOSFET with a separate heat sink, reduce device temperature, high current ability to work to improve the system; 3.3 using micro-controller; 3.4 SCM independent regulator chip, to avoid interference with BEC load caused by changes in supply and improve job stability microcontroller; 3.5 provide gold-plated motor connectors and heat shrink tubing DPM, easy to install (Note: This is optional equipment); 3.6 compatible Hooray Technology Brushless ESC Program Card. Package Include: 1 x Hobbywing Pentium-30A Brushless ESC TL2761
