DC Motor Speed Controller PWM Technology High Conversion Efficiency Wide Speed Range Motor Switch

Feature: 1. Using PWM speed control technology, high conversion efficiency, wide speed control range, stable performance. 2. Imported semiconductor chips are used and tested in terms of voltage, current, function, etc., the circuit is stable and reliable. 3. Potentiometer can be used to accelerate the positive and negative switches of forward, reverse and stop. 4. Safe to use, with overload and short circuit protection to protect the motor from damage and prolong the service life of the motor. 5. Wide speed range, reaching 5percent to 95percent , PWM frequency 500Hz, potentiometer resistance value B10K. Specification: Item Type: DC Motor Speed Controller Material: Printed Circuit Board Purpose: For DC Motor Speed Adjustment Model: CCM2 Working Voltage: DC10V30V Control Power: 12V x 3A=36W, 24V x 3A=72W, More Than 24A, Maximum 120W Rated Current: 3A Maximum Current: 4A Speed Adjustment Range: 5percent 95percent PWM Frequency: 500Hz Potentiometer: Resistance Value B10K Cable Length: Approx. 20cm 7.9in Output Voltage: About 0100percent of the Input Voltage Product Size: Approx. 74 x 47 x 28mm 2.9 x 1.9 x 1.1in. Package List: 1 x DC Motor Speed Controller1 x Switch1 x Knob1 x Nut1 x Washer Note: 1. The input of the DC motor speed controller is DC, and it cannot be directly connected to AC power (such as household 220V AC motor), otherwise it will burn out.2. The positive and negative poles of the DC power supply cannot be reversed, otherwise the governor will be damaged.3. The motor can be positive or negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the wire sequence.4. The potentiometer knob can change the duty cycle of the governor output, thereby changing the motor speed.Using PWM speed control technology, high conversion efficiency, wide speed control range, stable performance.
