testing report:
Then 12V
Current 9.8A, with the temperature rise, the current dropped to 8.8A (physical knowledge: resistance increases with the temperature increases)
Then 24V
Theoretical maximum current is less than 5A
If you use 24V, this the current is very large, MOS tube heat serious, it is easy because of high temperature burned.
In addition, consider whether the power supply is sufficient, to 576W power supply is very expensive, if the power supply is insufficient, may affect the motor and other equipment to normal operation.
