The switching power supplies are very good at taking just about any power with a reasonable voltage and just working. They take the input voltages and convert to DC pulses and really don't care much about the input so long as the HZ is above the rated HZ (usually 50 for non-US), and the voltage is not really high or really low. The only real issue is if the input voltage is significantly low and the output power is a high percentage of rated and the lower input voltage causes current draws that are at the high end of design. The switching power supply really eliminates a lot of the input power requirements (in computers). If the electronics do not have a switching power supply then linear power supplies are a lot less forgiving. In a linear power supply the transformer is first, in a switching the transformer is after the DC pulses so really does not care about wide frequency variations and voltage variations nearly as much. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
