MXA068 DC MOTOR SPEED CONTROL 50 AMP ADJUSTABLE FREQUENCY

FEATURES- Power supply : 8-30VDC.- Load voltage : 8-30VDC. / 50A. max.- Frequency can be fixed at 100Hz and adjustable from 400Hz to 3kHz.- Motor speed (PWM) can be adjusted from 0% to 100%- LED for power indication.- PCB dimensions : 3.42x4.92 in.
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 the 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-3kHz.- J1 is used for selecting the frequency. If J1 is jumping, the circiut can adjust the frequency from 400Hz to 3kHz, but if J1 isn't jumping, the
frequency will be fixed at 100Hz
