The TP-Link PSM900‑AC 900W AC Power Supply Module is a high-performance, hot‑swappable power unit engineered to deliver reliable and efficient power to enterprise-grade network equipment. Designed for use with compatible TP-Link Omada and Omada Pro switches, it converts standard AC input into stable 53.5V DC output, supplying up to 900 watts of power to support high‑density, power‑hungry network deployments. Built for maximum uptime and operational continuity, the PSM900‑AC features a fully hot‑swappable design, allowing installation or replacement without interrupting system operation. This makes it ideal for mission‑critical environments where network availability is essential. The module also incorporates comprehensive protection mechanisms—including over‑voltage, under‑voltage, short‑circuit, and over‑current protection—to safeguard both the power supply and connected devices. With its compact, rack‑mountable form factor and compatibility across multiple switch models, the PSM900‑AC offers a flexible and scalable solution for expanding or maintaining network infrastructure. Its robust design, combined with high output capacity and enterprise‑level reliability, makes it an excellent choice for data centres, large business networks, and other demanding applications that require continuous, stable power delivery.
