Prostar ET Series: The Future of Industrial Digital UPS

Prostar has meticulously developed the ET Series, a new generation of industrial-grade digital Uninterruptible Power Supply (UPS) systems. Designed for 3-phase input and output, these systems offer a power range from 10kVA to 200kVA and an advanced output power factor of 1.0, making them ideal for safeguarding critical loads in data centers, industrial automation, and communication infrastructure.

Core Technical Advantages

The ET Series represents a significant leap forward in UPS technology, integrating nine core technical advantages into a single, intelligent, and modular platform. This comprehensive approach ensures superior performance, reliability, and energy efficiency.

1. Digital Control Architecture

At the heart of the ET Series is its DSP (Digital Signal Processor) full digital control technology, which replaces traditional analog circuits. This digital transformation brings about stronger performance, higher control accuracy, and faster response speeds, effectively eliminating the issue of analog circuit parameter drift. The system's detection and control capabilities are significantly enhanced, comprehensively improving the UPS's reliability, power supply quality, and product consistency.

2. Advanced Inverter & Power Conversion

The system employs IGBT (Insulated Gate Bipolar Transistor) inverter technology combined with Space Vector Pulse Width Modulation (SVPWM). This ensures efficient and stable power conversion. The Double Conversion Pure Online Technology guarantees that the load is always supplied with clean, regulated power, while the SCR (Silicon Controlled Rectifier) Static Bypass Technology provides a seamless transfer path during maintenance or overload conditions, ensuring continuous power delivery.

3. Intelligent Battery Management

The Advanced Battery Management Technology is designed to prolong battery lifespan. It features charge management that is precisely tailored to the battery's charge and discharge characteristics. Additionally, the Combined Utility & Battery Power Supply Technology allows users to set the distribution ratio between utility power and battery power, making the UPS particularly suitable for environments with weak utility grids or large loads.

4. Green Power & Energy Efficiency

The ET Series incorporates Green Power Technology and supports ECO (Economic) Mode. In this mode, the system's efficiency can reach up to 98%, significantly reducing energy consumption and operational costs. This makes it an environmentally responsible choice for facilities aiming to minimize their carbon footprint.

Operational Flexibility & Reliability

The ET Series is engineered to handle a wide variety of load conditions with ease and reliability, ensuring uninterrupted operation even in challenging environments.

5. Strong Load Adaability

The UPS demonstrates strong load adaptability, capable of carrying motor and impact loads. It supports 100% unbalanced loads, including scenarios where one phase is fully loaded while the others are idle, or any two phases are fully loaded. This flexibility is crucial for industrial settings where load distribution can be uneven.

6. Robust Protection & Monitoring

The system is equipped with a Self-Detection Function to ensure safe initial startup. It also includes a Fan Failure Alarm that promptly notifies users of any cooling system issues, preventing potential system failures. The Comprehensive UPS Protection Technology safeguards against various power anomalies.

7. Parallel & Network Capabilities

The Parallel Function Support allows multiple UPS units to be connected in parallel, providing redundancy and scalability for growing power needs. The Network Monitoring Technology enables remote management and monitoring through various interfaces, including RS232, RS485, CAN, USB, dry contact, SNMP card, and WiFi/GPRS card, meeting diverse operational requirements.

User Experience & Maintenance

The ET Series prioritizes user convenience and system maintainability, incorporating intuitive interfaces and user-friendly designs.

Conclusion

The Prostar ET Series Industrial Digital UPS is a testament to the evolution of power protection technology. By leveraging DSP digital control, advanced IGBT inverters, and intelligent battery management, it delivers unparalleled reliability, efficiency, and adaptability. Its support for ECO mode with up to 98% efficiency, parallel redundancy, and comprehensive monitoring makes it a future-ready solution for industrial, data center, and critical infrastructure applications. With its user-friendly interface and modular design, the ET Series not only meets but exceeds the demands of modern power protection, ensuring continuous and stable operation in an increasingly digital world.
