- Standby UPS: The low-cost standby UPS provides basic protection against AC blackout, power sag, and voltage surge. It’s most commonly used for a single workstation, ATM/kiosk, IP telephony, and POS terminal. Lowell Series: UPSA6-850 ; UPS6Li
- Line Interactive UPS: The UPS for mid-range protection includes automatic voltage regulation (AVR) and protects against AC blackout, power sag, voltage surge, brownout, and over-voltage. It’s most commonly used for servers, small networks, IP telephony, POS terminals, and POE equipment. Lowell Series: UPS8, UPSV, UPSVLi

UPS Batteries: Lithium-ion v. Lead Acid
- Lithium-ion Batteries: Lithium batteries provide twice the service life of lead acid batteries, while offering better performance at higher temperatures, faster recharge, and a lighter/smaller footprint. They’re more economical when considering total cost of ownership.
- Lead Acid Batteries: The initial cost of a UPS with lead acid batteries is typically less than one with lithium-ion batteries; however, the units are typically larger, heavier, and have a shorter lifespan.
