DC motor speed controller

DC motor speed controller
Product Detailed
DC motor speed controlleris designed for battery-powered low-voltage high-power direct current motors and reversible Dc Motor.

The circuit is designed for battery-powered low-voltage high-power direct current motors, use of micro-processing chips and PWM impulse width special chip integration, signal processing, sampling to protect and promote the circuit more complete and reliable, while improving energy efficiency Conversion ratio.   FEATURES: PULSE WIDTH MODULATION Lower form factor than SCR drives. Motor runs quieter, with greater efficiency and less maintenance. FOUR QUADRANT REGENERATIVE OPERRATION REGENERATIVE BRAKING ENABLE / BRAKE / DIRECTION TERMINALS STATUS LEDs OVER TEMPERATURE PROTECTION    DRIVE PARAMETERS: DC Input Voltage [V]: DC20-62V DC Output Voltage [V]: 0 - 100% of Input Continuous Current [ A ]: 50A/100A (Derate by 20% when mounted horizontally. ) 1 Minute Peak Current [A]: 110A/240A Speed Regulation: 1% Speed Range: 80: 1 Ambient Temperature [° C]: 10-40   CONNECTIONS:   STEP 1: Connect speed potentiometer along with optional Brake and Direction switches As shown in above diagram. Connect 10k/2w potentiometer STEP 2: Connect motor armature across A1 and A2. STEP 3: Connect battery to ( BAT + ) and ( BAT - ), taking note of the polarity. KEYA Drives recommends adding a fuse and master power switch external to the drive. STEP 4: Connect Enable switch or jumper.    POTENTIOMETER ADJUSTMENT INSTRUCTION 1. MIN SP is the lowest rotation speed setting adjustments 2. Adjust potentiometer REV MAX SP(FWD MAX SP)to set motor biggest speed of motor 3. Adjust potentiometer DECEL to set soft stop. 4. Adjust potentiometer ACCEL to set soft start. 5. Adjust potentiometer IR COMP to set torque.
