Application Summary AI generated
GB/T 21225-2007 specifies technical requirements, test methods, and safety criteria for inverter-based emergency power supplies (EPS) used to provide backup AC power during mains failures. It applies to static inverter systems in commercial buildings, industrial facilities, and public infrastructure where critical loads like lighting, fire alarms, or life safety equipment require uninterrupted operation. The standard ensures reliability and performance consistency for EPS units rated up to 1000V, covering design, efficiency, and environmental endurance testing.
