What is an uninterruptible power supply?
Uninterruptible power supplies, also known as UPS, are used to provide backup power and protect electrical apparatus from power outages. They can also regulate and protect the attached equipment from abnormal voltages.
Some UPS systems can also regulate...
What size UPS do you need?
Power ratings for UPSs range from 300VA to 5,000kVA in volt-amperes (VA). This rating indicates the maximum load that a UPS can handle, however, it should not be used to determine the precise power load you have. The best practice is to purchase a UPS...
What type of UPS should I choose?
There are three main types of UPS systems: Offline, Line Interactive and Online.
