The air ESC with SBEC


The Graupner Ultra 20 A SBEC is the ideal speed controller for each airplane model, which need a power supply for the receiver. The ULTRA 20 A SBEC encloses a compact construction, low weight, super fast reaction times and settings optimized for airplane models.
The Ultra Regler is provided with the Open Source BLHeli Main Software in the version 14.x. The speed controller obviously be flashed with BL Heli MULTI or TAIL. The airplane ESC is the only Open Source Electronic Speed Controller which uses the modern 50 MHz Silabs processors and which can be adjusted and updated through the Graupner Update cable 7168.6; it is also provided with a power devider (0.109) for the voltage measurement with the appositely conceived receivers e.g. 33565, 33575 or Copter Flight Controls (e. g. Betaflight Setting: 92). The processor has a twice higher clock rate if compared to the previous model. This grants higher maximum RPMs so as precise timing at high RPMs.
The power amplifier is located in a 5 x 6 DFN housing. The field effect transistors (FET) have an extremely low internal resistance. Special FET drivers ensure a more effective active freewheeling and better cooling of the amplifiers.
The special capacitors used allow fast start-up times and guarantee high operating safety.
The control paths have already been optimized for the Graupner receivers.
The speed limit of the ULTRA controllers is 400,000 rpm with two-pole motors.
The SBEC is designed for 3A continuous current and can withstand short-term peak loads of up to 6 small servos.
An additional voltage sensor cable allows the voltage measurement and warning with the GR-12 SH or GR-12 SH Gyro receiver with the setting C5: Voltage. This feature is absolutely unique in this controller's category and it allows you to recognize a battery that is empty, thus protecting your model.

Characteristics:
  • Open Source BL Heli Software 14.2
  • 50 MHz Silabs processor
  • Power SO8 FETs amplifiers
  • Internal resistance typ. 1.6 mOhm
  • Special FET drivers
  • Ultra Low ESR capacitors
  • PPM receiver impulse and OneShot
  • Multishot available with update
  • PPM min and max throttle already set for Graupner receivers.
  • Spannungssensorkabel für die Voltage messurement feature with Falcon 12, GR-12, GR-16 and GR-18 receivers
