Overview
50 Amp DC Motor Speed Controller using pulse width modulation.
Feature
Power Supply: 8 - 30VDC
Load Voltage: 8 - 30VDC / 50A max.
Frequency can be fixed at 100Hz or adjustable from 400Hz to 3kHz
Motor speed (PWM) pulse width modulation can be adjusted from 0% to 100%
LED power indication
PCB Dimensions: 3.42 x 4.92""

Connecting and Tuning
Point +BATT is to be connected to the positive pole of power supply 8-30VDC
Point +L is to be connected to the positive pole of DC motor.
Point -L is to be connected to the negative pole of DC motor
Point -BATT is to be connected to negative pole of power supply
VR10K is used for adjusting the speed of DC motor (PWM) 0 - 100%
VR100K is used for adjusting the frequency from 400Hz to 3kHz
J1 is used for selecting the frequency.
If J1 is jumped, the circuit can be adjusted.
If J1 is not jumped, the circuit will be fixed at 100Hz.

NOTE:
Use electric wire No. 12AWG to connect between the circuit and load.
When adjusting the frequency to high, the MOSFET will get hot easily.
We recommend to use the frequency at 100Hz)
If the frequency is adjusted to higher than 500Hz, a mini fan should be installed on the heatsink.

This has been a very popular module for Hydrogen Fuel cells. Use this module to regulate the amount of current going into your Hydrogen fuel cell to prevent overheating.
