Product Introduction: The Architecture of Uncompromising Reliability

 

The Prostar PET Series represents a significant evolution in High Frequency Three Phase UPS technology. Moving beyond the limitations of traditional designs, it is built from the ground up for the modern, power-hungry, and highly sensitive electronic equipment that defines today’s critical infrastructure. At its core is a pure double-conversion topology, which means the load is always powered by the inverter, providing a continuous, clean, and stable sine wave output, completely isolated from any disturbances on the incoming utility power. This is not a feature; it is the fundamental principle that defines its existence as a true Online UPS.

 

The series is available in a range of 10kVA to 60kVA, making it perfectly suited for medium-sized data centers, hospital wings, and advanced manufacturing lines. Its compact, tower-form factor belies its power, offering a high power density that minimizes footprint without sacrificing performance. The system is designed with the future in mind, featuring a flexible architecture that can be scaled to meet growing demands. This is achieved through its robust parallel operation capability, allowing up to four units to be connected in parallel with a shared battery bank, creating a single, highly redundant, and scalable power system. This approach provides the ultimate in N+X redundancy, ensuring that even if one unit fails, the remaining units can seamlessly take over the full load, guaranteeing uninterrupted operation.

Technical Deep Dive: The Engine of Intelligent Power Management

 

The technical sophistication of the PET Series lies in its intelligent, multi-layered control system. At the heart of the unit is a powerful Digital Signal Processor (DSP) that governs every aspect of its operation. This isn’t just about switching power; it’s about intelligent, real-time management. The DSP continuously monitors input voltage, frequency, and load conditions, making micro-adjustments to ensure the output is always perfect. This advanced control enables features like full-phase active Power Factor Correction (PFC), which not only ensures the unit draws power efficiently from the grid (reducing strain on upstream transformers and cables) but also contributes to a cleaner power environment for other equipment on the same circuit.

 

One of the most critical aspects of any UPS is its battery system, and the PET Series excels here with its 3-stage smart charging technology. This isn’t a simple on/off charger. It employs a sophisticated algorithm with three distinct phases: Bulk, Absorption, and Float. The Bulk phase delivers maximum current to rapidly recharge the battery after a discharge. The Absorption phase holds the voltage at a constant level to ensure the battery is fully saturated without overcharging. Finally, the Float phase maintains the battery at a precise, optimal voltage to keep it fully charged and ready for the next outage, while minimizing the stress that leads to premature aging. This intelligent management significantly extends the service life of the battery, reducing total cost of ownership.

 

For environments where energy costs are a primary concern, the PET Series offers an ECO Mode. In this mode, the unit operates with even higher efficiency, passing utility power directly to the load when it is within acceptable parameters, while still maintaining the ability to switch to inverter mode in milliseconds if a disturbance is detected. This provides a balance between ultimate protection and operational cost savings, making it an ideal choice for facilities with relatively stable power grids.

Application Scope: Where Uninterrupted Power is Non-Negotiable

 

The versatility and robustness of the Prostar PET Series make it an ideal solution for a wide array of industries where power quality and continuity are paramount. Its applications are not limited to a single sector but span across the most critical and demanding environments.

 

In the Data Center space, the PET Series is the perfect companion for server racks and network closets. Its unity power factor output is perfectly matched to the power supplies of modern servers and switches, which are designed to operate at PF 1.0. This compatibility ensures that the UPS is not oversized, leading to more efficient use of space and power. The ability to parallel units allows for the creation of a scalable power infrastructure that can grow with the data center, from a small server room to a large colocation facility. The integrated SNMP and other communication interfaces provide IT managers with real-time visibility into the power system’s health, enabling proactive maintenance and remote management.

 

For Medical Equipment, reliability is not just a feature; it is a requirement for patient safety. The PET Series provides the clean, stable, and uninterrupted power needed for sensitive diagnostic machines like MRI and CT scanners, as well as life-support systems. The pure sine wave output ensures that these devices operate without interference or malfunction. The dual AC input option provides an additional layer of security, allowing the UPS to draw power from two separate utility feeds, further minimizing the risk of a complete power loss. The 4.3-inch touchscreen provides an intuitive interface for hospital staff to monitor the system’s status at a glance.

 

In Industrial Automation, the PET Series protects Programmable Logic Controllers (PLCs), Human-Machine Interfaces (HMIs), and robotic systems from the voltage sags, surges, and transients that are common in factory environments. Its high short-circuit resistance and robust construction make it suitable for these harsh conditions. The intelligent battery management system ensures that the system is always ready to handle unexpected power outages, preventing costly production downtime and potential damage to expensive machinery.

The Prostar Solution: Beyond Power, Towards Intelligence

 

Prostar doesn’t just sell a UPS; it provides a comprehensive power protection solution. The PET Series is a key component in a larger ecosystem designed to give customers complete control and peace of mind. The 4.3-inch full-color touchscreen is more than just a display; it is a command center. It provides an intuitive, user-friendly interface for monitoring real-time data such as input/output voltage, frequency, load percentage, battery status, and runtime. This allows operators to quickly understand the health of their power system without needing to consult complex manuals or external software.

 

For remote management and integration into larger building management systems, the PET Series offers a rich set of communication interfaces. Standard ports include USB and RS-232, while optional modules provide RS-485 and SNMP connectivity. This allows the UPS to be monitored and controlled from anywhere in the world, sending alerts via email or SMS for any critical events. The system also features a built-in Emergency Power Off (EPO) function, which allows for the immediate shutdown of the UPS in case of a fire or other emergency, ensuring the safety of personnel and equipment.

 

Finally, the PET Series is designed with serviceability in mind. The modular design of its internal components, combined with the intelligent diagnostics, means that maintenance is faster and less disruptive. The system can self-diagnose many potential issues, alerting technicians before a failure occurs. This proactive approach, coupled with the ability to perform maintenance without shutting down the load (thanks to the maintenance bypass switch), minimizes downtime and maximizes the availability of the critical systems it protects. This is the essence of the Prostar solution: intelligent, reliable, and designed for the real-world challenges of modern power management.
