Line interactive UPS designs seem to offer adequate voltage regulation and conditioning. Why should I consider even greater protection?
The protection a line interactive system offers is significant, but sometimes isn’t enough. Some types of sensitive electronic equipment, such as measurement equipment, medical equipment and networking hardware, demand the highest levels of regulation and conditioning. A UPS whose output is 10% more than the nominal input voltage might cause these types of equipment to go into failure and shut down. When you can’t afford the risk consider online protection.
