1500VA 120V UPS systems provide the maximum power capacity supported on a standard 120V 15A circuit using a NEMA 5-15P connection. These systems deliver up to 900–1450W of usable output and are widely deployed for network infrastructure, AV systems, retail environments, and distributed edge applications where plug-and-play installation is required.
Key Advantages
- Designed for standard 120V 15A circuits (NEMA 5-15P input)
- Delivers up to 1450W of usable output depending on model
- Plug-and-play deployment without electrical upgrades
- Available in tower, rackmount, and compact 1U configurations
- Extended runtime available on select models
- Lithium (LiFePO₄) options available for long service life
Typical Applications
- network switches, routers, and firewalls
- AV and control system equipment
- retail POS systems and kiosks
- small IT and edge infrastructure
- medical carts and mobile systems

Runtime Considerations
Typical runtime varies based on load and battery configuration:
- 600W load: approximately 10–20 minutes
- 900W load: approximately 5–15 minutes
- Extended runtime available on select models with external battery packs
For exact runtime calculations, use the UPS Selector.
Extended Runtime Capability
Models supporting external battery packs include:
P80-1500, T91-1500, and P91-1500.
Maximum UPS by Circuit Type
A standard 120V 15A circuit using a NEMA 5-15R receptacle supports UPS systems up to approximately 1500VA (900–1450W depending on system design). This defines the upper limit for plug-and-play UPS deployment without requiring electrical modifications.
For higher-capacity systems, 20A circuits or 208V power may be required.

Key Selection Considerations
- Circuit type and plug compatibility (5-15P required)
- Required runtime and battery expansion
- Form factor (tower vs rackmount vs 1U vs short-depth)
- Battery technology (VRLA vs lithium)
- Installation environment and temperature
Lithium vs VRLA Battery Options
Lithium UPS systems provide longer service life, higher cycle capability, and improved performance in elevated temperature environments compared to traditional VRLA batteries.
