Feature:1. PWM high-efficiency DC motor speed control module, stepless speed change, PLC speed regulation.2. The 50V/1000uF large capacitor has obvious advantages compared to other types of speed governors of 100-200uF.3. Use 1RF3205 power tube, use 8500 high current terminal, the power is stronger.4. Advanced technology, high efficiency, high torque, low heat, low noise, is widely applied to industrial production.5. Manufactured from premium pcb materials for a long service life and stable performance.Specification:Conditon: 100% Brand NewItem Type: Speed Control ModuleMaterial: PCBColor: As Pictures ShownCircuit Board Size: Approx. 76mm x 45mm/3.0 x 1.8inInput Voltage: DC12-48VOutput Current: 0-20AType of Speed Regulation: Flow RegulationSpeed Range: 0-100%Wiring Type: Fence Type TerminalOutput Voltage: Linear Under LoadContinuous Power: 1200WSpeed Regulation Method: Potentiometer (Linear)Control Frequency: 25KHZRotary Knob Specifications: 097 (0-100% Speed Regulation).Package List:1 x Speed Control Module
