Note:
SMPS peak power is 40A 480W, avoid overload, recommended for equipment under 34A 400W. For resistive equipment, the power supply power ≥ equipment power x 1.25 times. For motor equipment, the starting current will be much higher than the rated power and the peak power of the SMPS needs to exceed 2 times the motor power.
NOTE:Not suitable for charging Battery, Speed Control Motors.
