Pure Sinewave Online UPS Zero Transfer Time 5400W with Built in Lead Acid Battery

Operating in pure online mode, this UPS delivers pure sine wave AC output through advanced rectification, filtering, and voltage stabilization processes. This technology effectively filters out grid disturbances including voltage surges, noise, and transient fluctuations, preventing precision equipment failures caused by poor power quality.

During power outages, the system seamlessly switches to internal battery power with zero milliseconds interruption, ensuring continuous operation for servers, industrial control systems, precision instruments, and other critical equipment.

The unit integrates high-quality sealed lead-acid batteries, eliminating the need for additional battery cabinets and cables. This space-saving design reduces deployment costs and is ideal for server rooms and office areas with limited space.

• Default full-load runtime: 2 minutes (adjustable based on load)
• Supports external battery packs for extended runtime requirements
• Flexible adaptation to various power supply needs

Features an ultra-wide mains input range of 110V-300V, specifically designed for environments with significant grid fluctuations such as industrial sites and remote areas. This wide range reduces frequent battery mode switching, extends battery lifespan, and lowers equipment damage risks from grid issues.

Comprehensive built-in protection mechanisms safeguard both equipment and UPS system:

• Overvoltage and undervoltage protection
• Overload and short circuit protection
• Overtemperature monitoring
• Battery overcharge/overdischarge protection
• Reverse connection protection

Standard high-definition LCD display provides real-time monitoring of key operational parameters:

• Mains and output voltage
• Load rate and battery capacity
• Operating mode status
• Fault information display

Intelligent alarm functionality provides audible and visual alerts during grid anomalies, low battery voltage, or overload conditions for prompt troubleshooting.

Designed for 24/7 continuous operation with intelligent fan speed control technology that automatically adjusts based on load and temperature conditions. The system operates with minimal noise disruption while achieving conversion efficiency exceeding 98%, delivering significant energy savings for long-term power supply applications.
