4. Technical Principles and Innovative Values:

The SECAP 2000PLS incorporates advanced technical principles and innovative features that set it apart in the industrial power supply market:

• Innovation Point 1: Automatic Load Sharing and Redundancy: A core innovation of the SECAP 2000PLS is its capability for fully parallelable operation with automatic load sharing. This intelligent feature ensures that when multiple SECAP 2000PLS units are connected in parallel, they distribute the load evenly, maximizing their lifespan and efficiency. Crucially, in the event of a failure in one module, others instantly compensate, maintaining uninterrupted power to the load. This far surpasses non-parallelable power supplies, offering unparalleled system uptime and reliability.
• Innovation Point 2: Integrated Redundancy Diode: Each SECAP 2000PLS module includes an internal redundancy diode on its output. This critical component provides an additional layer of reliability by decoupling a faulty module from the load. If an internal short circuit occurs on a module’s output, this diode ensures the load continues to operate without disturbance from the affected unit, a significant advantage over power supplies requiring external redundancy modules.
• Innovation Point 3: Advanced Overtemperature Protection: The SECAP 2000PLS features a sophisticated three-threshold overtemperature protection circuit. This multi-stage approach, sensitive to the module’s internal temperature, first activates an internal fan, then triggers an alarm signal, and finally initiates a controlled shutdown if temperatures reach critical levels. This proactive protection mechanism safeguards the power supply and connected equipment, enhancing operational longevity and preventing catastrophic failures, a more comprehensive solution than simple thermal shutdown.

5. Application Cases and Industry Value:

In a modern data center managing critical cloud infrastructure, consistent and clean power delivery to server racks is paramount. The facility frequently experienced minor voltage sags and power supply aging, leading to unexpected server reboots and data integrity concerns. By integrating the SECAP 2000PLS power modules into their distributed power architecture, configured for N+1 redundancy, the data center significantly enhanced its power resilience. The automatic load sharing ensured optimal performance across all active modules, extending their lifespan. When a power fluctuation occurred, the redundant SECAP 2000PLS units seamlessly picked up the slack, preventing any discernible impact on server operation. This implementation led to a 99.99% uptime for their critical servers, drastically reducing data loss incidents and IT maintenance costs associated with power-related issues, directly contributing to improved service level agreements and customer satisfaction.
