Buying Guide
- Load requirements: Determine the total wattage of devices you intend to back up. Choose a UPS with a comfortable margin above that load to avoid automatic shutoffs during short outages.
- Output type: Consider whether your gear benefits from a stepped sine wave, simulated sine wave, or pure sinewave output. Sensitive electronics and active PFC power supplies often perform best with sinewave or pure sinewave inverters.
- Outlets and layout: Look for a mix of battery-backed and surge-only outlets to maximize protection for critical devices while preserving flexibility for less essential equipment.
- Management features: LCD displays, USB charging ports, and software integration help monitor power conditions, perform graceful shutdowns, and maintain uptime.
- Voltage compatibility: Most US-based models run on 120V nominal input but may accept 110-240V. Verify compatibility with your building’s electrical system and any 240V equipment you intend to power directly or through the UPS.
- Protection protections: Seek models with surge protection, overcurrent protection, and voltage regulation (AVR) to guard against spikes and sags common in 240V supply environments.
- Physical footprint and noise: Larger units provide more runtime but take more space and may generate more audible fan noise. Choose based on your installation constraints.
- Battery life and replacement: Check expected runtime at your typical load and the availability of replacement batteries, along with the service life of the UPS.
For installations that span multiple devices with varying power needs—such as door access controllers, network gear, and workstations—pairing a UPS with a regulated DC supply can enhance reliability. Ensure you select models that support your specific devices and voltage requirements, and consider units with AVR and robust surge protection to maintain stable operation during grid fluctuations.
