Feature: *Excellent quality: Made of pure copper internal conductor and high -quality circuit board, with reliable performance. *Multifunctional design: Our DC motor speed controller can be used with various motor (9V-60V) and has switching functions to increase convenience. *Safety and effective: Through automatic fuse protection and linear output under load, our controller can provide up to 20A continuous power (1200W). *Easy to install: Our compact module (77mm x 45mm x 28mm) is lightweight (73G) with potentiometer to easily adjust (0-100 %). *Make sure that the positive and negative connection is correct before power on. Do not touch the heat dissipation tablet for the wiring, and you may burn the circuit board. Note that this is not a power module. You must connect to the motor to adjust the speed. The output of the meter volume of the motor has not changed. Specification: Input voltage: DC10-60V Output voltage: Loading down linearity Output extreme current: 20A (10A for a long time, within 450W, pay attention to keeping the module smooth heat dissipation conditions) Extreme power: 1200W Speed adjustment : potentiometer (linear) Control frequency: 25KHz Wiring type: fence -type wiring terminal Paper line length: 20cm Module size: long*width*height 77mm*45mm*28mm Weight: 73 grams Motherboard is installed in size: length*width 73mm*40mm The potentiometer opens the hole: 7mm Input: 9-60v DC Power: Power+ P ower - Motor: M otor + M otor - Package included: 1*DC motor speed regulator 20A Note: 1. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2. Please allow slight manual measurement deviation for the data. 3.This speed regulator is used for the use of a brush motor. 4.It is not suitable for the speed adjustment of the DC brushless motor; it cannot be used as a regulator or a regulator! _x000D_ _x000D_
