Uninterruptible Power Supply (UPS) is a pretty common backup power supply in industrial settings where “power failure” can lead to the loss of control systems, emergency
shutdown systems, and emergency mitigation systems. But like ALL SAFEGUARDS we take credit for in our Hazard Analyzes, these UPS must be in our mechanical integrity program for testing/validation regularly (e.g., manufacturer’s frequency).
BSEE has become aware of a series of failures in industrial uninterruptible power supply (UPS) systems, resulting in significant power loss to industrial control systems, emergency
shutdown systems, and emergency mitigation systems. These incidents have also led to capacitors and battery failures, compromising critical systems’ reliability and effectiveness.
