High-Performance Line-Interactive UPS for Network, AV, and Distributed IT (700VA – 1500VA)
Engineered for Power Stability
The S71 Series is more than a simple battery backup. It is a line-interactive UPS specifically engineered for environments where utility power is inconsistent. By combining reliable battery ride-through with Automatic Voltage Regulation (AVR), the S71 stabilizes incoming power without depleting the battery, ensuring your critical equipment stays online during brownouts and surges.
- Capacity: 700VA, 1000VA, 1500VA
- Voltage: 120V Single Phase
- Form Factor: Compact Tower
- Topology: Line-Interactive with AVR
Key Features & Technical Advantages
Why Choose the S71 Series for Your Infrastructure?
- Automatic Voltage Regulation (AVR): Constantly monitors and corrects voltage fluctuations (brownouts and overvoltages) to provide consistent 120V output, extending battery life significantly compared to standby models.
- Fast Transfer Times: A typical 4ms transfer time ensures that sensitive electronics—from retail POS systems to AV servers—stay powered during transitions.
- Intuitive LCD Interface: Real-time monitoring of AC mode, battery status, load levels, and input/output voltage directly on the front panel.
- TAA Compliant: Meeting the requirements for government and federal projects.
- Comprehensive Warranty: 3-year warranty on both electronics and batteries (USA & Canada), providing peace of mind for long-term deployments.
Best Applications for the S71 UPS
Optimized Power Protection for Distributed Environments
1. Retail & Point-of-Sale (POS) Systems
Voltage fluctuations in retail environments can cause system crashes and data loss. The S71-1000 provides the stability needed for cash wraps, barcode scanners, and payment terminals, ensuring transactions never stop during a brownout.
2. Distributed IT & Network Closets
Small network clusters, routers, and switches require constant uptime. The S71-700 is the ideal “enhanced entry” solution for edge locations that need more protection than a basic standby UPS but don’t require a full rack-mount online system.
3. Audio Visual & Digital Signage
Protect expensive AV equipment from the “dirty power” often found in commercial buildings. The line-interactive topology of the S71-1500 ensures clean, stable power for media players, amplifiers, and high-definition displays.
4. Security & Surveillance
Security cameras and NVRs are critical 24/7 assets. The S71 protects these systems from power surges and outages, ensuring that your facility remains monitored even when the grid fails.
