What is UL 956?

UL 956 refers to a specific safety standard that is used to evaluate and certify uninterruptible power supply (UPS) systems. These UPS systems are crucial in providing backup power to critical equipment or systems, ensuring uninterrupted operation even during power outages or disruptions.

Importance of UL 956 Certification

The UL 956 certification ensures that the UPS systems meet stringent safety and performance requirements. It guarantees that the equipment has undergone rigorous testing and evaluation by an independent third-party organization, such as Underwriters Laboratories (UL), which is recognized globally for its expertise in product safety testing.

In today's digital world, where sensitive electronic devices and critical data are vulnerable to power disturbances, having a reliable and certified UPS system is essential. Businesses and organizations rely heavily on these systems to protect their equipment and maintain operations, thus making UL 956 certification significant.

UL 956 Testing and Criteria

The testing process for UL 956 certification involves evaluating various aspects of the UPS system. This includes assessing its electrical performance, resilience to power surges and fluctuations, as well as its ability to withstand different environmental conditions.

During the testing, the UPS system is subjected to simulated power outage scenarios and assessed on parameters like battery runtime, transfer time, voltage regulation, and fault protection. The equipment is also evaluated for compliance with electrical safety standards, such as overheating prevention, short circuit protection, and insulation resistance.

Benefits of UL 956 Certified UPS Systems

Choosing a UL 956 certified UPS system brings several benefits. Firstly, it ensures the safety of not only the connected electrical equipment but also the individuals operating or working in close proximity to the system. The certification guarantees that the UPS system meets strict safety standards, reducing the risk of electrical hazards.

Secondly, the certification assures users of the system's reliability and performance. By meeting rigorous testing criteria, UL 956 certified UPS systems demonstrate their ability to deliver continuous power supply, even under challenging conditions. This capability ensures that critical equipment, such as servers, telecommunications infrastructure, and medical devices, remain operational during power disturbances.

In summary, UL 956 certification is an essential factor to consider when selecting a UPS system. It provides confidence in the product's safety, reliability, and performance, ensuring the uninterrupted operation of critical electronic devices and systems.
