As AI rapidly advances, data centers have become the core infrastructure for immense AI computation. The power consumption of these chips is skyrocketing, making a stable power supply and an efficient cooling system equally critical. Among these, the Coolant Distribution Unit (CDU) is essential for maintaining optimal temperatures within AI data centers, and Delta’s Force-GT DIN rail power supply plays a crucial role by providing a core driver for these CDUs.

Coolant Distribution Unit (CDU): the cooling core for data centers
The Coolant Distribution Unit (CDU) serves as the central cooling hub for modern AI data center liquid cooling systems, much like a car engine's cooling system. It functions as a dedicated radiator for high-performance servers. The CDU adopts integrated pumps, heat exchangers, sensors, and smart control systems to precisely manage the coolant's temperature, pressure, and flow. By continuously supplying chilled coolant to the data center’s high-speed "engines," this system removes heat more efficiently than air cooling. It prevents overheating and hardware damage, therefore ensuring the stable and continuous operation of AI computation.

The quiet achiever behind CDUs: the Force-GT Series DIN rail power supply
The Force-GT series DIN rail power supply is the "unsung hero" supporting the liquid cooling CDU during the complex cooling process. The entire series features both single and three-phase models, and provides a power range from 120W to 960W and 12V to 48V output options. Notably, the 480W/24V and 48V models achieve 80 PLUS Industrial 115V Platinum certification, leading the global market of DIN rail power supplies. Furthermore, the Force-GT series' high conversion efficiency of up to 95% significantly reduces overall energy consumption, delivering significant benefits for AI data centers prioritizing Power Usage Effectiveness (PUE).

A major advantage is the Force-GT's extremely low derating, a feature that makes it a heat-tolerant runner who doesn't need to "slow down" in high temperature. A typical runner can maintain 100% speed in cool weather but must automatically slow down to 70% or 80% in high temperature to avoid collapsing. This "slowing down" mechanism is similar to a power supply's derating curve. With the Force-GT series' extremely low derating, the single-phase model only derates by 2.5% per degree Celsius above 60°C, and the three-phase model derates above 55°C. By maintaining a stable, near-full-load output even in extreme heat, the Force-GT not only reduces energy costs but also eliminates the need for an additional backup. It thus guarantees high reliability and uninterrupted power in demanding data center environments.With up to 95% conversion efficiency, the Force-GT series DIN rail power supply provides stable power to liquid-cooled CDUs.

For now, the Force-GT DIN-Rail series power supplies have been successfully adopted by leading manufacturers in the industrial control and thermal management industries, delivering consistent and stable power.  With a spirit of innovation, Delta is committed to developing more efficient and reliable power solutions, hence driving the industry's progress by strengthening the backbone of a sustainable AI ecosystem.
