40 Controls & Timers High Power Motor Speed Controllers (PWM) ✔ Control the speed of a DC motor without sacrificing torque! ✔ Soft-Start feature for extended motor life! ✔ Available in 15A, 30A, and 50A models! These powerful Pulse-Width-Modulation (PWM) DC motor speed controllers provide continuous current to your DC motor or other DC load. Models are available to handle up to 15 amps, 30 amps, or a whopping 50 amps! Thanks to a digital microcontroller based (PIC) design and highly efficient High-Power MOSFETs for cooler operation, these controllers will give you all the torque you need at any speed!. They can operate in either Fixed or Variable frequency modes - the fixed frequency mode runs the controller at 100 Hz, and in the variable frequency mode of operation the frequency can be adjusted from 244 Hz to 3.125 KHz. Duty cycle is fully adjustable from 0% to 100% in both modes. SPECIFICATIONS Supply/Load Voltage: 6-24VDC (12VDC recommended) Max Continuous Current: 15A/30A/50A @ 100Hz Duty Cycle: Adjustable from 0-100% PWM Duty Cycle Range: 0-100% Frequency: 100 Hz or 244Hz to 3.125KHz Dimensions: 2.98” x 1.41” / 3.02” x 1.88” / 4.03” x 2.82” Wired & Tested The Ultimate Bi-Directional Motor Controller! This unique bi-directional DC motor speed controller is based around a Microchip PIC microcontroller at the heart of the circuit controlling a full H-Bridge power stage using four high-power efficient MOSFETs. The controller allows you to control both the Speed and Direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0 to 100% (both Positive and Negative DC output). It can deliver a maximum continuous current of about 7A out of the box, and up to 10A to 15A with the addition of an optional fan and reinforcement of PCB tracks! Traditionally, switches are used to reverse the polarity of the voltage applied to a DC motor in order to change the rotation direction. However, this method requires use of DPDT switches and causes the voltage applied to the motor to suddenly change from full positive to full negative. The sudden change while the motor is spinning leads to a high level of mechanical stress on the motor, as well as high current surges that can cause damage to any electronics in the path. This circuit is different! Using a full H-Bridge circuit, the solid-state design of this motor speed controller does not use any mechanical switches, and it allows control of both speed and direction through a single potentiometer. At its center position, the motor will be forced to stop (i.e. it brakes), as opposed to a floating/coasting state, and the motor terminals will be grounded. Wired & Tested Great for HHO, DC/LED Light Dimmers, Heating Control, etc.! UK1115 UK1130 UK1133 The controllers also offer a built-in soft-start feature that greatly reduces the mechanical stress on the motor, not to mention the electrodynamic stress on the attached cables and battery - this means longer life for the whole system! An optional fan is available for the UK1115 and UK1130 models, and is recommended for continuous operation at maximum power or for high frequency at high current applications. The UK1133 comes pre-equipped with a fan, and can also accept an optional LCD Display Module that displays current frequency and duty cycle. From CanaKit.

SPECIFICATIONS Supply/Load Voltage: 6-24VDC (12VDC recommended) Max Continuous Current: 7A @ 100Hz Duty Cycle: Adjustable from 0-100% in both directions PWM Duty Cycle Range: 0 to +/- 100% Frequency: 100Hz or 200Hz Dimensions: 3.02” x 1.88” Turning the potentiometer clockwise causes the motor to start spinning slowly in the positive direction, with increasing speed up to the maximum supply voltage at its maximum position. Turning the potentiometer in the counter-clockwise direction will cause the motor to spin in the reverse direction, again starting slowly up to a maximum negative supply voltage. As an added option, the controller allows for selection of two operating PWM frequencies: 100 Hz or 200 Hz. From CanaKit. UK1125 7A Bi-Directional Motor Speed Controller (PWM), Factory Assembled & Tested $39.95 5A Motor Speed Controller (PWM) KIT ✔ LED brightness to indicate speed ✔ Adjustable speed via built-in pot ✔ Compact size for easy integration This DC motor speed controller uses the popular 555 Timer Integrated Circuit to generate a Pulse-Width-Modulated (PWM) output voltage with adjustable duty cycle in order to control the speed of a DC motor without sacrificing torque. SPECIFICATIONS Supply/Load Voltage: 6-16VDC (12VDC recommended) Max Continuous Current: 5A @ 140Hz Duty Cycle: Adjustable from 1-99% Frequency: Approximately 140Hz Dimensions: 1.77”x 1.18” Wired & Tested Powerful Control in a Compact Package! Incorporating a high power MOSFET with a heat sink, this controller can easily provide a continuous current of 5A to your DC motor or other DC loads such as high-power LEDs or LED strips for dimming applications. The circuit also includes an LED speed indicator - the brightness varies in proportion to the relative speed of the motor, giving you a handy indicator of the current speed. The PWM frequency is approximately 140 Hz, with the Duty Cycle adjustable from approximately 1% to 99%. From CanaKit.
