Parameters:Operating Voltage Range: DC 6-26V (maximum 28V), suitable for 2-6S lithium battery packsOperating Current: Rated 15A, maximum 25A (forced air cooling), instantaneous 30AOperating Power: 100-300W (related to the supply voltage; lower voltage = lower power; higher voltage = higher power)Maximum Speed: Maximum speed is related to the number of motor poles and the KV value of the motorPotentiometer Speed Control Function: Continuous speed controlButton Start/Stop Function: Yes, each press switches the device between start and stop. The speed at start-up is the speed set by the potentiometerOverload Protection: YesInput Under-Voltage Protection: None (version with LCD display can set input under-voltage protection)Overcurrent Protection: None (version with LCD display can set overcurrent protection)Hall Sensor: None0-5V Analog Speed Control: 0-3.3V input, 0-5V requires a 9.1K resistor in seriesSpeed Control Potentiometer Resistance: 10K - 100KInput Reverse Connection Protection: None. Please note the positive and negative terminals when wiring. Note:1. There are various types of brushless motors. One driver cannot control all brushless motors. This driver is not suitable for brushless motors with high rotational speed and large magnetic resistance. If you are unsure whether your motor can be used, please connect a smaller fuse in series with the power supply and test if it can start normally when the motor is unloaded. If it cannot start normally, it is not suitable for this motor.2. The driver has a reverse rotation protection function. However, please do not manually reverse the motor when it is rotating at high speed. There is a risk of burning the MOS transistor.3. When the motor is rotating at high speed, press the start/stop button. The instantaneous current is very large. In this case, the MOS transistor may be damaged due to the excessive impact current. Please use the one-click start/stop function when the rotational speed is below 50% of the full speed.4. Do not use this driver beyond the input voltage. The input has a TVS diode, which can effectively prevent the driver from being broken by the surge voltage during the motor start/stop. Do not connect motors with significantly mismatched power to prevent the driver from burning out.
