What is a True On-Line UPS?

A true on-line UPS constantly runs connected equipment on recreated AC power. In short, the UPS converts incoming AC utility power into DC power and then back into clean AC power to operate your equipment. This “double-conversion” process ensures consistent power quality that’s completely isolated from any utility power disturbances. If the utility AC fails, the UPS continues to run using it's internal battery system.  MINUTEMAN’s MCP-E Series and MINUTEMAN’s MCP Series are both true on-line UPS systems.
