 25A Bi-Directional Speed Controller PCB Model V2! 
 
Note: This model (Internal case model) has NO external connections for things like hall effect controllers or external potentiometers. If you have ordered this model by mistake and want to swap it for another type (eg. Model A, B, C external case model etc) there will be a $25 charge to swap it over. So MAKE sure your selection is correct! 
 
Four Quadrant (4QD), Large Current Capacity, Ultrasonic switching speeds (No more whiney motors!) Electronic Braking, Battery Regen, Control type calibration and more!

Features at a glance:

  • Wide voltage range 12.0V-36.0V
  • Full Speed Regulation with linear range control from 0 to 100%
  • Hand assembled in Australia, utilising a heavy duty industrial grade alloy metal case (case model only)
  • Reverse Polarity Protection for main drive circuits, Control circuitry protection, protected against EMF spiking up to 600 Volts!
  • Optional Soft start for forward and reverse directions!
  • Maximum Current of 25A (capable of sustaining short burst loads up to 40A!)
  • Ultrasonic! High Frequency PWM Removes the “whine” caused by oscillating motor windings, even at low speeds!
  • 2 Oz 4 Layer PCB with heavy copper traces for low resistance and high current capacity!
  • High Speed, 2 AMP N-Channel Mosfet driver!
  • 8x High Current 180 Amp 75V Mosfets with the worlds lowest RDS On in TO-220 (4 for 25A model)
  • Four Quadrant motor control
  • Regenerative - Power generated from the motor is fed back to the source for longer lasting batteries          
  • Low voltage driver shutdown, protecting the high speed switching drivers against sagging or failing batteries!
  • Internal voltage filtering with Transient Clamping Protection to ensure stable and reliable control at all times!
  • Eight Way Terminal Connector; For quick and secure connections, suitable for most terrains!

 

This smart little controller packs quite a punch and despite the fact that designing it certainly drove us crazy, it was a challenging project while it lasted. It was designed to fill a niche in the market! There are a lots of bi-directional controllers available out there in the wild, thats not the issue, but there is simply no GOOD ones available at a decent price. Really! I'm not making this up, they simply don't exist!

Whilst designing this controller, It became apparent that it was getting harder and harder to stick to the original goals, simply because we kept trying to add more and more feaures as we progressed with the design. At the same time we were also trying hard to keep the overall cost of the units down compared to anyone elses offering (Don't forget, we use ALL genuine parts, not Chinese copies! so every part, no matter how small could add up quickly to blow the cost out FAST!)

So now with the V2 model, we we've 
taken (mostly) the same functionality of the original unit and improved on it even more! We now have provision to use a bigger heatsink if people plan on running it at its higher limits or slightly above for longer periods, more protection against people massaging the PCB while walking barefoot through plush carpet, protection on the inputs and we've also added mounting holes so that it can be more easily mounted, we've removed the need for the bracing on the bottom of the PCB, improved cooling efficiency and have made more subtle changes to increase reliability and useability.


Extremely good controller. Has been tested and abused by people to love to break things! Can be used for all different types of applications and is available in a variety of different flavours. Was built to be simple but reliable. COuld be doubled up to make a Jopystick controlled

 

Model Information:

Model C: 

This model uses its control method to change the direction. Consider a potentiometer with its 180 degree circle.
If you turn the unit from 0 degrees to 85 degrees you will be turning the controller in the reverse direction from FULL SPEED to the lowest speed.
From 85 degrees to 95 degrees you are turning all speed off. From 95 until 180 degrees you are turning  the controller  speed in the forward direction from its lowest speed to its highest speed.

Heavy duty Mosfet drivers! Heavy Duty Mosfets, Heavy Duty, heavy Duty, heavy Duty... And at a fantastic low price!

Easy to hook up and use!

Hand Assembled in Australia! Please note, these take a while to assemble and are one of the harder controllers for us to build, so it may take a day or so longer when you order this to actually make it!
