Description

The 1–3 kVA models come in an A4 format (RT), followed by the 6–10 kVA range. Input power factor is 0.99, while output power factor is 0.8, 0.9 or 1.0 depending on the model. Input voltage is 110–300 V AC, and 110–286 V for the 6–10 kVA models, so the UPS stays on mains longer when the grid sags and does not switch to battery. Efficiency reaches 94% in the 6–10 kVA RT versions. The case is built as tower or rack/tower. Versions with lead-acid and lithium batteries exist, as well as UL1778 and Energy Star variants for the US.

How to choose

Start by working out the load power, taking the output power factor into account. For a server at a factor of 0.9, multiply the apparent power in kVA by 0.9 to get kW. If you need 6–10 kVA with N+X parallel operation and a rotating display, look at the UCR. For a three-phase UPS of 10–80 kVA there is the UD, while the YDC3300 has efficiency up to 95.8% and runs in parallel with up to 8 UPS units.
