Omron S8BA-24D24D120LF 24 VDC 120 W Industrial UPS
The Omron S8BA-24D24D120LF is a compact DC-to-DC uninterruptible power supply developed to protect industrial computers, controllers and automation equipment against momentary voltage drops and power failures. It operates with a rated 24 VDC input and supports a rated output of 24 VDC, 5 A and 120 W.
Its integrated lithium-ion battery and DIN rail mounting structure make the UPS suitable for installation inside industrial control cabinets where reliable backup power and efficient use of panel space are required. During normal operation, the input voltage is supplied to the connected load. If the input supply fails, the UPS automatically switches to battery operation without an interruption in output.
Reliable Backup for Critical Control Equipment
Unexpected power interruptions can cause industrial computers, PLCs and controllers to stop before operational data is saved or the system is shut down safely. This UPS provides temporary backup power that can support controlled shutdown procedures and help reduce the risk of data loss, production interruption or equipment restart problems.
At an initial battery condition and an ambient temperature of 25°C, the specified backup time is approximately six minutes at the rated 120 W load. Actual backup duration can vary according to load level, battery condition, operating temperature and configuration.
