Design: DC motor governor can easily supply 2A continuous current to DC motors or other DC loads. With self-restoring fuse 2A and activated LED. PWM DC motor governor with switching function.Technical parameters: input voltage range: DC2.2 --- 12V, output voltage: 1.8 -- 12V adjustable (according to the power supply voltage), output current: Less than 2ANote: 1. Connect the DC motor tuner to the direct power supply. Do not connect directly to household 220V AC power supply, otherwise you will be responsible for the consequences 2, governor current: 2A, connect current greater than 0.5A, 775 motor, pram motor can not drive, please do not buy the wrong motor. 3, do not recommend the use of more than 12V power supply, such as 12V lead-acid batteries, otherwise it may damage the governor size: 32mm x 32mmMaterial: PCB, metalcolour: greenPackage Contents:5 x PWM DC motor governorOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
