The IBM 39J2576 is a 1475W Hot-Swap AC Power Supply designed to deliver reliable, high-efficiency power to IBM servers and storage systems. Engineered for high-performance computing environments, it ensures that your vital IT equipment remains operational, even in the face of power supply unit (PSU) failures, thanks to its hot-swap capability. This feature allows system administrators to replace or add power supplies without needing to shut down the server, thus maintaining uninterrupted service and availability. The 39J2576 unit supports automatic voltage regulation, accommodating a wide range of AC input voltages, and is equipped with overvoltage, overcurrent, and overtemperature protection circuits to safeguard your infrastructure. Its high efficiency not only reduces energy consumption but also minimizes heat output, contributing to a lower total cost of ownership by decreasing cooling requirements. The PSU's robust design and compatibility with a range of IBM servers make it an essential component for ensuring the operational resilience and energy efficiency of your data center.
