Long-Term Uninterruptible Power Supply

Background

In many critical applications, such as seismic monitoring and infrasound stations, there is a paramount need for reliable power backup solutions to ensure continuous operation during power outages or disruptions. These systems often rely on 12V DC equipment, which necessitates an uninterrupted power supply to maintain data integrity and operational stability. The reliability and uptime of these installations are crucial, especially in remote or demanding environments where access for maintenance may be limited.

However, current uninterruptible power supply (UPS) technologies often fall short in meeting the extended runtime requirements of such applications. Traditional UPS systems typically provide backup power for only minutes, which is insufficient for prolonged outages that can last several hours or even days. Additionally, existing solutions may suffer from limitations like bulky sizes due to modular designs, inadequate climate resilience restricting their use to controlled indoor environments, and cumbersome processes for configuration and firmware updates. These shortcomings hinder the deployment of UPS systems in harsh or remote settings, thereby compromising the reliability and effectiveness of essential monitoring equipment.

Technology

The rack-mountable, battery-backed Uninterruptible Power Supply (UPS) system provides extended runtime power backup for 12V DC equipment, supporting durations from hours to over a week. Available in Full and Mini versions, the Full UPS includes twelve 12V battery outputs at 100W each, four regulated 12V outputs at 75W per port, and six AC outlets rated at 300W each. Key features encompass a 120V AC input, multiple 12V battery connections, a robust AC-DC power supply, and a DC-AC inverter with optional higher capacity. The double-conversion design ensures uninterrupted power flow. Additionally, it integrates a Power Distribution Unit with relay-controlled outputs, advanced SNMP and web-based monitoring, per-battery management, self-testing, temperature sensing, and Ethernet connectivity. Designed for 19” rack mounting within a 5U space, it is ideal for applications requiring high reliability and extended backup, such as seismic and infrasound stations.

This UPS system stands out by offering significantly longer backup durations compared to conventional solutions that typically provide only minutes of power. Its advanced monitoring and management capabilities, including Remote State of Health monitoring and comprehensive battery oversight, enhance reliability and simplify maintenance. The double-conversion design improves power quality and stability by preventing direct AC flow. Proven in critical environments like International Monitoring System stations, it demonstrates exceptional performance and durability. Furthermore, its modular design allows for scalability, and seamless integration with existing infrastructures provides a competitive edge over major manufacturers by meeting specific needs for extended and reliable power backup.
