HobbyKing 20A UBEC User Manual

Dear customers:
Thank you for using the smart power electric speed controller (ESC) for brushless motor designed and
produced by HobbyKing.com. Wrong use and operation may cause personal injuries and damages on the
equipment due to the strong power at the starting of the product. We strongly recommend customers to read the
specification carefully before using the product and operate the product strictly in accordance with the
operating provisions. We assume no responsibilities generated from the application of the product, including
but not limited to liabilities for damage of incidental losses or indirect losses. Meanwhile, we assume no
responsibilities generated from the disassembly and modification by users themselves and assume no
responsibilities caused by products from the third party.
We have the right to alter products including appearance, performance parameter and operating requirement
without advanced notice. We make no guarantee, declaration or promise on whether the product is suitable for
specific purpose of users.
I. The main properties of electric speed controller for brushless motor
● Use powerful and high-performance MCU processor. The users can set function of use according to their
requirements. It fully reflects the smart property of our products as a unique advantage.
● Support unlimited rotate speed of brushless motor
● Support the function of fixed speed
● Delicate circuit design with strong anti-interference
● The starting mode can be set. The response speed of throttle is very quickly and with very stable linear of
speed regulation. It can be used in fixed wing aircraft and helicopter
● Threshold values of low-voltage protection can be set.
● With internal SBEC, the operating power to start steering engine is strong and the power dissipation is
small.
● Multi protection function: protection for abnormal input voltage/ protection for low battery/ protection for
overheat/protection of lowing power when lost of signals from throttle
● Good safety performance under energization: the motor will not start at the time of power on regardless of
the location of pull rod of throttle in controller.
● Protection for overheat: the output power will lesson to half when the temperature reaches 100
operation of ESC. The output power will automatic recover when the temperature is under 100℃
● Supports with operation setting for all controller and setting of programming panels
● Set alarm sound. And judge the working situation after power on.
● The company has completed intellectual property on the product. The product can be continuingly updated
and upgraded. The product can be made to customers' requirements.
