If you are from outside US our EUR based listing may be more favorable for you.
You can find our the EUR based listing here with many other subversion of this controller:
>Crocodile FR5050 EUR listing<
- H-Bridge reversible direction controller
- 4 operation modes: normal potentiometer or hall throttle (with 0.8-4.2V output)/joytick mode/direct PWM input (0-95%)/ RC PWM receiver input 1,5ms +/-1ms
- Fully controllable via serial communication with more adjustable parameter on TX RX connector.
- 4 quadrant operation Drive or regenerate in forward direction. And drive or regenerate in reverse drection.
- High speed 32bit Cortex processor.
- 18kHz switching frequency
- Duty cycle: 0-100%
- Overheating protection. 70°C/158°F
- Universal 0-5V speed control input. You don't have to use the potentiometer to controll the speed. You can use PLC
output or any analoge signal or PWM signap from uPC or RC receiver PWM signal. - Regenerative braking (you can brake the motor and get back all the kinetic energy into the battery)
For the highest safety the regenerative braking never replaces the normal brake! - Adjustable ramp speed (acceleration limit). 0-40seconds
- Normal current limit is adjustable between 0-50A
- Peak current 100A.
- Universal supply voltage between 6-50V DC.
- Dimensions: 107 x 75 x 30mm
- For the maximum power you have to add extra heatsink to the aluminium block!
- 150g
For those who wants to use serial communication simple Arduino command mode or Advanced command mode communication protocoll is available. Find both protocoll documentation in the datasheet. The following parameters are available by read/write registers:
- Motor speed
- Current limit/regenerative current limit
- Acceleration/deceleration limit
- Turn ON/OFF minimum and turn ON/OFF maximum voltage levels for example turn off the unit at low battery voltage
- Heatsink and Motherboard temperatures
- Supply voltage
- Potentiometer input voltage (you can use this input for an analoge measurement input if you are controlling the speed with RS232/485 commands )
- Output current
- Input frequency on PWM input
- Input duty on PWM input
- I x R compensation (this if for speed regulation compensation the load drop voltage)
- Top output voltage / supply compensation (maximum speed limit) (this can be very usefull in more cases. As you give a maximum reference voltage (maximum RPM) what the output can be with the maximum gas setting. This value becomes a reference voltage and archive perfect supply voltage compensation. This means if your supply voltage drops of raise your motor PRM remains the same. Using the supply compensation and the I x R compensation together you can archive perfect speed regulation without any closed loop feedback and no tachogenerator is needed.
- Status register
- Configuration bits
- Adjustable serial address controlling more controllers on one line.
- Current calibration register
For more information and how to use the serial communication please read the datasheet with the controll registers.

Difference between DC motor controllers?
There are many type of controllers the most piece is a chinese simple and cheap controller. They are great until you put a large load to theirs output.
-Those controllers does not have proper supply filtering with many capacitors what is very important! Without supply capacitors the most of the chinese controllers regularly burning down.
-They does not have proper freewheele diode system against the motor inductive current!
-The most of them does not have any current limit or thermal limit function which is very important to protect the motor and the controller as well.
-Most of tham has only one way to use with just a potentiometer to change the output voltage. No acceletartion limit, no regeneration function, no serial communication or other special controlling mode.
These controllers has all in one functions and we keep depevoling the units if any other request or market demand occurs!
How to use these controllers?
If you want you can set acceleration limits, voltage turn ON/OFF points, regenerations modes.
Also if you want you can use serial communication or PWM as a controll mode. Functionas are higly flexible.
With the current limit potentiometer you can very fine adjust the current what the motor can maximum consumes.
After this your motor and PWM driver is fully protected against the burning down or overload.
Additional protection is the temperature protection. The controller measures the temperature of heatsink. If that exceeds the maximum the controller will shut down.
Does it come with warranty what if you need help?
Yes. We test each controllers before shipping. If there is a problem it has 6 months warranty. If you have problem or question please feel free to contact. For installation you can find many informations in the datasheet which is available in the ad there is a download link in the desctription.
