The S8BA series of compact dc-dc UPS protects IPCs and PLCs from sudden power loss resulting from voltage drop or power failure. The DIN rail-mounting UPS uses a lithium-ion battery with a 10-year life expectancy. Maximum backup time can be programmed via the front of the unit to customize backup power performance. The UPS offers monitoring with a seven-segment display and beeper that indicate UPS status, battery charge level and error diagnostics. The unit has been designed to work in conjunction with 24-Vdc-output Omron S8VK series ac-to-dc power supplies or similar ones from other suppliers.
