Prostar ET HV Series: The Pinnacle of High Voltage Digital UPS Technology

In an era where power reliability is paramount for critical infrastructure, Prostar's ET HV Series High Voltage Digital UPS emerges as a robust solution. This in-depth technical article explores its architecture, performance metrics, and key advantages, positioning it as a formidable contender in the industrial UPS market.

Core Specifications at a Glance

Digital Architecture: The Heart of Reliability

The ET HV Series represents a significant leap from traditional analog UPS systems by embracing a fully digital control architecture. At its core lies a high-performance Digital Signal Processor (DSP), which replaces the less precise analog circuits. This digital brain enables faster, more accurate, and more stable system control, effectively eliminating the issues of parameter drift and slow response times that plagued older designs.

Complementing the DSP is the IGBT (Insulated Gate Bipolar Transistor) Space Vector Pulse Width Modulation (SVPWM) technology. This advanced power conversion method ensures superior output waveform quality, making the UPS compatible with a wide range of sensitive equipment. The combination of these technologies results in a system that is not only more reliable but also offers enhanced performance and consistency.

Unmatched Performance & Efficiency

Advanced Battery Management & Load Adaptability

The ET HV Series incorporates Advanced Battery Management Technology (ABM) . This intelligent system dynamically adjusts charging and discharging parameters based on the battery's characteristics, significantly extending its service life. Additionally, the system includes a fan failure alarm function, proactively notifying users to replace faulty components, thereby ensuring the UPS system operates reliably under all conditions.

The UPS demonstrates exceptional load adaptability, seamlessly handling diverse loads including motors, impact loads, inductive, capacitive, and non-linear loads. It supports 100% unbalanced loads , allowing for a single-phase full load or any two-phase full load configuration. This flexibility is crucial in real-world industrial and data center environments where load conditions can be unpredictable.

Comprehensive Protection & Communication Capabilities

The UPS is equipped with an automatic bypass function, ensuring continuous power to connected equipment even during overloads or various potential UPS fault conditions. This is a critical safety feature for maintaining uptime in mission-critical applications.

The ET HV Series offers extensive communication capabilities to meet diverse monitoring and management needs. It supports interfaces such as RS232, RS485, CAN, USB, dry contact, SNMP card, WiFi/GPRS card, and more. This allows for seamless integration into existing IT infrastructure, enabling remote monitoring, management, and alerts.

For user convenience, the system features a 7-inch LCD capacitive touch screen , providing an intuitive and convenient operating experience. Additionally, it includes complete data logging functionality, recording fault, operation, and status records, which greatly facilitates maintenance and troubleshooting efforts.

Key Applications & Market Position

The Prostar ET HV Series is specifically recommended for protecting critical infrastructure across multiple industries. Its high power rating, robust design, and advanced features make it ideal for safeguarding equipment in data centers, telecommunications hubs, computer networks, manufacturing plants, and financial institutions .

In the competitive landscape, the ET HV Series stands out by offering a compelling balance of high power capacity, industrial-grade reliability, and cost-effective efficiency. While other manufacturers like Huawei, Eaton, and Schneider Electric offer their own UPS solutions, the ET HV Series provides a specialized option for facilities operating on 480VAC systems, with particular emphasis on digital control and high-efficiency operation. 

Conclusion

The Prostar ET HV Series High Voltage Digital UPS is a sophisticated power protection solution designed for the most demanding environments. Its digital architecture, featuring a high-performance DSP and IGBT SVPWM, ensures superior control and output quality. With a focus on energy efficiency (up to 98% in ECO mode), robust battery management, and exceptional load adaptability, it provides reliable, cost-effective protection for critical infrastructure. The series' comprehensive communication options and user-friendly interface further enhance its appeal, making it a strong contender in the industrial UPS market.
