| For systems using a 24 V supply voltage, we recommend the use of a24v12or24v23 driver. When using18v17,18v15and18v25controllers, there is a risk that the voltage at some moments will exceed the permissible value of 24 V (e.g. when the batteries are fully charged), which may cause permanent damage to the system. |
Additives:
- Manualcontaining sample connections and source codes
- Adjustable start and maximum speed
- Option to prevent accidental starting of the engine
- Adjustable PWM frequency from 1 kHz to 22 kHz
- Can be turned off when the supply voltage is too low
- LED diode indicating the appearance of errors

Communication
HighPower series controllers can communicate through three interfaces:
Computer USB port
- Communication with a computer through a virtual COM port
- Sample codesin C #, Visual Basic, .NET, C ++
- Optional security (CRC control, timeout)
- Automatic detection of the baud rate (from 1200 bps to 500 kbps)
Remote Control - modeling apparatus
- Frequencies from 10 to 333 Hz
- Adjustable parameters for RC signal
- Two channels
- Possibility to power the receiver from the BEC system (BEC jumper)
Analog interface
- Resolution: 12 bits
- Voltage range: 0 to 3.3V
- Two analog channels
