2000VA / 2200VA 120V UPS Systems for 20A Circuits
A dedicated 120V 20A circuit supports up to 2000–2200VA — the 80% continuous load rule limits a 20A breaker to 16A continuous, which is 1,920W at 120V. Five platforms cover this capacity across line-interactive, online, and lithium topologies.
Five platforms — find the right one for your application
All five platforms are rated for 120V 20A circuits with a NEMA 5-20P plug. The differences are topology, battery chemistry, form factor, and runtime capability. A 20A dedicated circuit is standard in IDF closets, server rooms, and commercial AV installations — giving you more headroom than a standard 15A receptacle.
Line-interactive topology in a convertible rack/tower form factor. The 2200VA model delivers the highest output wattage in the line-interactive 20A class — up to 2000W. External battery packs extend runtime beyond the internal battery. Right choice for cost-sensitive IT, retail, and light industrial deployments where online double-conversion isn’t required.
Online double-conversion — zero transfer time, continuous power conditioning. Tower form factor for locations where a rack isn’t available. External battery packs extend runtime. The right choice for sensitive equipment in a tower deployment where online protection is required but a rack is not an option.
Online double-conversion in a convertible rack/tower form factor. External battery packs extend runtime. The standard rackmount online UPS for network infrastructure, AV systems, and distributed IT at this capacity — where online topology is required but lithium isn’t specified. Well-suited to IDF closets and server rooms on dedicated 20A circuits.
Same form factor and topology as the P91 with LiFePO₄ battery chemistry — up to 15-year service life in ideal conditions, 3,000–5,000 cycles, 50°C operation. The right choice when the P91’s performance profile fits but battery replacement across distributed sites is operationally unacceptable. Lower total cost of ownership across multi-site deployments.
Online double-conversion in a 1U form factor with switchable outlets for remote reboot of individual devices. Standard internal LiFePO₄ battery plus support for external battery packs — delivering extended runtime at typical network loads. LiFePO₄ battery, 50°C operation, no routine replacement. The most capable 1U platform at this capacity for network racks and IDF closets where extended runtime is required.

| Platform | Topology | Battery | Form factor | Ext. runtime | Best for |
|---|---|---|---|---|---|
| P80-2000 / 2200 | Line-interactive | Lead acid | Rack/tower | Yes | Cost-sensitive IT, retail, light industrial |
| T91-2000 | Online | Lead acid | Tower | Yes | Online protection, tower-only deployments |
| P91-2000 | Online | Lead acid | Rack/tower | Yes | Network, AV, distributed IT |
| P91Li-2000 | Online | Lithium | Rack/tower | No | Distributed, high-temp, long lifecycle |
| J90-2kLiD | Online | Lithium | 1U rack | Yes — external pack | Network racks, remote reboot, extended runtime |
Typical runtime at 2000VA · 120V
Runtime depends on actual load — not UPS capacity. A 2000VA UPS running a 500W network load runs significantly longer than the same UPS at 1500W. The J90 2kVA supports external battery packs for extended runtime — the same capability available on the lead acid P80, T91, and P91 platforms, now available in a 1U lithium platform.
