Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If rack-mounted complete UPS unit
Assembled UPS systems over 1kVA classify under complete static converters.
If for automatic data processing units
UPS PCAs designed specifically for ADP machines classify under Chapter 84.
If standby-only switching function
Offline/standby UPS without continuous conversion are control panels, not converters.
