Essential Considerations for Selecting UPS Systems in Harsh Environments

When it comes to selecting an Uninterruptible Power Supply (UPS) for applications in rugged and harsh environments, reliability and durability are paramount. Design engineers working in critical infrastructures such as surveillance systems, network equipment, cell tower backup power, and gas supply facilities require UPS solutions that can withstand extreme conditions and provide uninterrupted power protection. Here are essential factors to consider when choosing a UPS for these demanding environments.

1. Temperature Resilience

Operating environments in industrial settings can experience extreme temperatures. It’s crucial to select a UPS that can operate efficiently within this wide temperature range. Look for UPS systems specifically designed to withstand such conditions without compromising performance. A UPS like the SANUPS A11K-Li Series, which is engineered to function seamlessly in harsh temperatures, offers a wide temperature range of -20 to +55℃, ensuring continuous operation even in challenging environments.

2. Battery Lifespan and Maintenance

Traditional UPS systems often rely on lead-acid batteries that require frequent replacements every 5 years, leading to potential downtime and maintenance costs. In contrast, UPS solutions with advanced lithium-ion battery technology, such as the SANUPS A11K-Li, offer a maintenance-free lifespan of 10 years(*). This extended battery lifespan not only reduces the risk of power interruptions during replacements but also minimizes maintenance expenses, making it an ideal choice for critical applications in rugged conditions.

3. Reliability and Safety

Select a UPS system equipped with robust protective features to ensure high reliability and safety. Look for dual protection mechanisms like those found in the SANUPS A11K-Li Series, which integrates both UPS and Battery Management System (BMS) protections. These safeguards protect against overcharging, overcurrent, and excessive temperature rise, ensuring optimal UPS performance and longevity even in the harshest environments.
