Miniature Pwm 12 Volt DC Motor Controller 72W Dc Speed Controllers

Miniature Pwm 12 Volt DC Motor Controller 72W Dc Speed Controllers

Miniature pwm controller 0~100% adjustable drive module 12v dc motor speed controller dc motor controller

Features:

• Using PWM speed control technology, with high conversion efficiency, wide speed range, and stable performance.
• Adopting imported semiconductor chips, and had tested the voltage, current, function etc. So the circuit is stable and reliable.
• Overload short circuit protection and the current no more than 30 seconds.
• Potentiometer is used to speed up the positive and negative switch for forward, reverse, and stop.
•

• resistor mounting hole: 8mm
• Voltage: DC 10V-30V( wide range)
• Working voltage: 12v*3A=36W/24V*3A=72W Maximum up to 120W
• Rated current: 3A(Maximum continuous output current)
• Maximum current: 4A
• Modulation range: 5%-95%
• PWM frequency: 500HZ
• Module size: approx.74*47*28mm/2.91*1.85*1.10''
• Gross weight: approx. 33g

Note:

• DC motor speed control input is DC, can not directly connect AC current (such as the 220V AC) otherwise it will burn.
• The positive and negative poles of the DC power supply can not be reversed, Otherwise the governor will damage.
• Motor can be divided into positive and negative, when the direction of operation and expectations are inconsistent, you can change the direction of the alignment.
• The potentiometer knob can change the output duty cycle of the governor, thus changing the speed of the motor.
• Please allow 1-3mm differs due to manual measurement.
