ESC HobbyWing Platinum V4 25A
Top programmable microprocessor controller for AC motors without sensors ("brushless, sensorless") constructed using the possibilities of the most modern semiconductor technology with excellent utility properties and extensive programming and setting options. It is used to control the speed of AC electric motors in larger and giant models of airplanes or helicopters when powered by NiCd/NiMH and Li-poly/Li-ion/Li-Fe batteries. It is designed with high long-term load capacity and durability in mind, which is required in competition and giant models. For helicopters, it offers an advanced governor function with a number of adjustable constant speed control parameters. It is equipped with a high-performance switching power supply stabilizer BEC with an adjustable output voltage ensuring the power supply of the receiver and servos from the drive battery. For easy adjustment of the controller, use the special Multifunctional LCD programming box Hobbywing or the Wi-Fi module WiFi Express, which are supplied separately.
DESCRIPTION AND FUNCTIONS OF THE REGULATOR
Suitable for the vast majority of aircraft AC motors powered by 3-6S LiPo batteries.
High-performance microprocessor with a clock frequency of up to 72 MHz for precise governor function (maintaining constant speed) and super soft start.
A special power stabilizer for the microprocessor for high resistance to interference and to reduce the risk of loss of control.
DEO (Driving Efficiency Optimization) optimized control technology significantly improves throttle response and power stage control efficiency, reduces regulator temperature.
New switching power supply stabilizer BEC with output voltage adjustable in the range of 6.0 or 7.4 V and a load capacity of 3 A continuous / 7 A peak.
The BEC is separated from the other circuits of the regulator, it can maintain the correct function even if the power board with MOSFET transistors of the regulator is burnt.
Extensive programming options with a wide range of adjustable functions and parameters.
Flight Modes: Airplane, Helicopter (Linear Throttle), Helicopter (Elf Governor), Helicopter (Store Governor)
The new governor program with adjustable P/I governor parameters brings excellent maintenance of constant revolutions, guarantees stable revolutions of the carrier rotor even with sudden changes in load.
The flight data recorder records rpm, minimum voltage and maximum temperature during flight.
The "autorotate restart" function can manually interrupt the autorotation and quickly restart the motor to avoid a crash caused by improper model control.
Independent output port for tachometer signals.
Special programming port for programming the controller or setting the parameters of the Multifunctional LCD programming box or Wi-fi Express module.
Supports online data check, controller programming, firmware update on PC or smartphone/tablet (requires Multi-function LCD programming box or Wi-fi Express).
Wi-fi Express Wi-fi module (sold separately) for wireless programming of the controller using your smartphone (iOS or Android).
A number of protection functions: start-up protection, controller thermal protection, capacitor thermal protection, overload protection, control signal loss protection, etc.
PROGRAMMABLE FUNCTIONS
Flight Mode: Allows you to select programs for airplanes, helicopters (with linear throttle control), helicopters (with Elf governor) or helicopters (with Store governor).
Number of LiPo cells: The regulator offers automatic detection of the number of cells or its manual setting.
Method of disconnecting the motor when the voltage protection is activated: The controller will gradually reduce the power to 50% of full power within 3 seconds after the voltage protection is activated, if the "Power Limit" mode is selected. If the "Hard Shutdown" mode is selected, the engine is immediately shut down.
PCO - Voltage protection: The threshold level of voltage protection is adjustable in the range of 2.7-3.7 V/cell.
BEC Voltage: The BEC voltage of the power stabilizer is adjustable between 6.0V or 7.4V.
Response time: This function is used to adjust the throttle response, the higher the value, the slower the throttle response.
Governor parameter P: Determines the ability of the governor to maintain a stable speed.
Governor parameter I: Determines the dynamic response of the governor.
Auto Restart Time: In Helicopter (Elf/Store Governor) modes, the governor shuts down the engine when the throttle is between 25 and 40%. If you add throttle above 40% during the preset auto restart time, the engine will start quickly and (during the set restart acceleration time) accelerate to the rpm corresponding to the current throttle value. If you add throttle above 40% after the preset auto restart time, the controller will go into soft start.
Restart Acceleration Time: Adjustable between 1-3s in 0.5s increments. This function determines the time the engine takes to restart and accelerate to full speed in Helicopter (Elf/Store Governor) modes.
Brake: Sets the function of the propeller brake - off, normal, proportional, reverse (allows to turn on the reverse of the engine operation using another channel with a switch).
Braking intensity: Adjustable between 0-100% in steps of 1% for Normal brake mode.
Timing: Adjustable
