48V 500W Brushless Motor Controller DC Driver for CNC Spindle BLDC Motors Speed Control Module

Specifications: Rated voltage: 20 to 50 VDC Rated current: 12A Current limiting: 15A Maximum speed: 20000RPM( the specific speed depends on the motor itself and load) Storage temperature: -20?~+65? Usage environment: Avoid direct with dust, fumes and corrosive gases Temperature: 0-45? Humidity: <80%, no frost, frost Shock: 5.9m/ Storage humidity: 0~95%RH Size: 9.5 * 6 * 3.5cm / 3.74 * 2.36 * 1.38inch Weight: 258g 1.Two modes of speed regulation: External potentiometer: through this potentiometer speed regulation; External voltage: external 10VDC voltage speed regulation; Note: The two speed regulation can not be used simultaneously 2. Speed output PG : There is a 5v-revolution pulse output between the port and the ground. The output frequency is set to P (Hz), the motor class logarithm is N, and the speed is F (RPM), then the output speed frequency is P=F*N/60. 3. Alarm output ALM :There is an 5V alarm pulse output between the port and the ground. 4. Positive inversion function: F/R:Fiddle the toggle switch on the corresponding side, the motor steering direction can be changed. For the toggle switch, the white part is up and down, then it up and down. For the toggle switch, the white part is horizontal, and the horizontally. 5. Start-stop 1. External switch EN: Transfer through switch. 2. Side toggle switch EN: for the toggle switch, the white part is up and down, then down for the start; for the toggle switch, the white part is horizontal, then dial to start?Note: You can only turn one control at the same time, one of the switches is closed, and the other one is valid.? 6. Locked-rotor :If the motor stops working, switch on the power again to start. 7. Power light: Green light: power on and off

• Protection: Motor controller includes over voltage over current and locked rotor protection.
