PDU Testing and Research Process

Industry professionals verify performance claims through a combination of rigorous laboratory testing and real-world simulations. High-Temperature Operating Life (HTOL) and Intermittent Operating Life (IOL) tests validate long-term reliability under stress. Accelerated Life Testing (ALT) predicts operational lifespan by exposing devices to extreme conditions. Electrical safety assessments focus on insulation, grounding, and overload protection. Independent organizations, such as UL and CE, certify products after evaluating them against established standards. Manufacturers also provide detailed testing reports, which offer transparency and support informed decisions. These processes ensure each PDU delivers consistent performance and meets strict safety and environmental requirements.
