3-Phase Pure Sine Wave Double-Conversion Online UPS Series with Thyristor-Based Static Bypass
Product introduction:
This UPS system delivers pure sine wave output through a double-conversion online topology, providing critical loads with voltage-stabilized, frequency-regulated power free from grid disturbances. During grid failures, it seamlessly inverts battery energy to maintain uninterrupted output.
Featuring a high-frequency double-conversion design with an output isolation transformer and advanced fully digital control technology, it ensures stable, clean, and reliable power. The user-friendly interface supports customizable configurations and real-time monitoring, while integrated communication options include MODBUS, RS232, and expandable intelligent slots for flexible connectivity.
The system architecture integrates:
Engineered for precision and resilience, this UPS guarantees mission-critical power continuity in industrial, data center, and telecom environments.
