KTA-246 Mini DC Motor Speed Controller in Box
With this kit control the speed of any common DC motor rated up to 30V and 8A without sacrificing motor torque.  Operates on a supply voltage of 8V to 30V.
Uses a microcontroller to accurately pulse-width modulate a high current power MOSFET, IRFZ44.
Also features adjustable acceleration time, potentiometer, 0-5V or 4-20mA input signal control.
Die Cast Box mounted. Finished Dimensions (mm): 35Wx89Lx30H.

KTA-194 Hi Current DC Motor PID Speed Controller
Provides feedback control of DC Motors. Operates in Closed Loop PID mode or Open Loop PWM mode.
Target Speed and PID settings are set via the Pushbuttons and LCD, Serial Port or Analog Input (potentiometer).
With this kit you can control the speed of a common DC motor rated up to 55V (20A) without sacrificing motor torque.  Operates on a supply voltage of 8V to 26V.
Uses a microcontroller to pulse-width modulate two high current power IRFZ44 MOSFETs to provide high torque DC Motor Speed Control.
Feedback is achieved with a Photo-Interrupter Pulse (Provided).
Please Note - This speed controller is not suitable for controlling the speed of gearhead DC motors using feedback because of the slow pulse rate from the photo interrupter.
 
Finished Dimensions (mm): 100Wx100Lx40H.

KTA-195 Hi Current DC Motor PWM Speed Controller
This DC motor controller uses PWM Pulse Width Modulation to control the speed of a DC motor. A potentiometer can be used to set the speed or a 0 to 5VDC or 4-20mA signal can be supplied.
With this kit you can control the speed of a common DC motor rated up to 55V (20A) without sacrificing motor torque.  Operates on a supply voltage of 8V to 26V.
Uses a microcontroller to pulse-width modulate two high current power IRFZ44 MOSFETs to provide high torque DC Motor Speed Control.
Now PWM Frequencies of 9.7KHz, 1.2KHz, 152Hz and 38Hz can be selected using DIP Switches.
This controller is suitable for controlling Golf Buggy DC Motors. A customer recently said this was the best controller he had used with his Golf Buggy Motor.

KTA-207 Serial Hi Current DC Motor PWM Speed Controller
The operation of this 20A DC Motor Speed Controller is configured using a serial port of a PC. It has 4 different modes of operation.

Mode 0 - Speed is set by ASCII commands received from a serial RS232 connection. Up to 4 Speed Controllers can be addressed and controlled from a single PC or microcontroller serial port.
Mode 1 - 4 selectable speeds can be chosen using a 4 position rotary switch
Mode 2 - Motor speed is controlled by a 1-2mS RC Pulse.
Mode 3 - Motor speed is controlled by a PWM pulse stream received from a PLC or microcontroller

With this kit you can control the speed of a common DC motor rated up to 55V (20A) without sacrificing motor torque.  The controller logic operates on a supply voltage of 8V to 26V. It uses a microcontroller to pulse-width modulate two high current power IRFZ44 MOSFETs to provide high torque DC Motor Speed Control.
PWM Frequencies of 9.7KHz, 1.2KHz, 152Hz and 38Hz can be selected using a serial command.

A straight through D9 Male to Female serial cable is required to configure and communicate with the controller via a PC. The PC software supplied is a Visual Basic program with source code provided for you to be able to write your own programs to control the motor from your PC.
