What is the smallest 3-phase UPS available?

Most UPS manufacturers supply a three phase UPS from 10kVA or 10kW upwards. This unit will either be only available as a 3/3 (3phase-input/3-phase output) or a 3/3 and 3/1 (3-phase input/1-phase output) system. When installing a UPS capable of 3/3 or 3/1 configuration, the final set-up is usually made during installation either through hardware or hardware and firmware settings.
