* Note: The duty cycle is tested at 40°C has been determined by simulation.
* Note: The Machine with PFC version, can works under the input voltage from 85V to 260V.
While the input voltage is lower than 145V, it will switch to low voltage working mode
automatically, and the output power will be limited. Please restart the machine to recover
to the full output power, after input voltage gets to be higher than 145V.
