It delivers up to 10A max current with smooth speed adjustment from 10% to 100% duty cycle via a potentiometer knob. Built-in protections against reverse polarity, over-voltage, and overload fuse ensure reliable and safe operation. Ideal for industrial automation, DIY projects, and motor speed tuning, it combines robust performance with a minimal heat footprint. ## Description Feature: Module Size: 60x55x28mm Work Voltage: DC 12V-40V Rated Current: 8A Max Current: 10A Quiescent Current: 0.02A (Standby) Output Voltage: Approx.0%-100% of input voltage Speed Range: 10%-100% PWM Frequency: 13KHz PWM Pulse Width Speed Range: 10%-100% Power Range: 0.01-400W Knob Potentiometer: Resistance B100K, Trepanning 8mm Fuse Wire: 5x20mm 10A Adopting 50V 1000uF large capacitance,with power supply reverse polarity protection, over-voltage protection funcion. Reserved lead type knob interface, if use lead type knob, it need to dismantle the fixed potentiometer first. Suitable for DC motor speed control etc. Note: DC power supply polarity can not be inversed, otherwise is may damage speeder. Not suitable for AC power supply. Package List: 1pcs 12V-40V 10A DC Motor Speed Controller Review: Fixed mig welder wire feed! - Used this to replace a bad wire feed motor driver board on a Harbor Freight Mig170 welder. I secured the old board out of the way with wire ties as it has other circuitry on it that still works. I installed this board using the potentiometer nut in the original hole. I installed a 24vdc power supply (240vac rated) to the pains terminals and wired the output in series with the trigger wire. It fed wire perfectly and brought the welder back to operation. I did add some hot glue to support the board and prevent it from touching anything. It is nice that it has a heat sink to keep it cool as the original one did not. Great little board and appears to be well built. Review: Just What I Needed - Too early to tell about long term reliability, but this worked great for me. I'm using it to control an 18V drill motor. My power supply is a 20V laptop power supply, and this is giving me an output of about 4 to 18.5V, with maximum amps at about .5A. Can't say if that ~7% voltage loss is reasonable, but it is not a problem for me. The speed control is very linear. Not getting any heat anywhere in the setup. ## Features - Type: DC 10A 12V-40V motor speed controller, high efficiency, high torque, low heat radiation. - Function: With power supply reverse polarity protection, over-voltage protection, 10A standard fuse over-load protection, more safer and reliable. - PWM Duty Cycle: 10%-100%, Control Power: 0.01-400W, adopting variable speed knob potentiometer to control motor speed. - Rated Current: 8A, Max Current: 10A, Quiescent Current: 0.02A (Standby) - Applications: Suitable for DC motor speed control, PLC speed control etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0779QXYSR | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #111,551 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #82 in Motor Speed Controllers | | Customer Reviews | 4.3 4.3 out of 5 stars (176) | | Date First Available | November 9, 2017 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 2.82 ounces | | Item model number | SPEEDER-10A | | Manufacturer | DZS Elec | | Material | lead | | Package Dimensions | 4.41 x 2.56 x 2.28 inches | | Part Number | SPEEDER-10A | | Size | 10 Amp | ## Images ![DZS Elec 10A 12V-40V DC Motor Speed Controller 12V 24V PWM Variable Speed Regulator Governor Switch CCMHCN With Speed Control Knob - Image 1](https://m.media-amazon.com/images/I/71rYgoVV49L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fixed mig welder wire feed! *by M***L on November 4, 2020* Used this to replace a bad wire feed motor driver board on a Harbor Freight Mig170 welder.
