GW Instek ASR-6600-18 - 18 kVA AC/DC Rack Type Power Source
The Inception of ASR-6000 High Performance AC/DC Power Source Development
From the very moment Alpha Go defeated the human chess champion with its ultra-high-speed computing capability, artificial intelligence technology (AI) has developed rapidly around the world. Today, servers with advanced AI functions process tremendous amounts of data under the high-speed computing architecture of 2 CPUs + 8 GPUs.
However, AI servers require a huge amount of power to maintain high-speed computing! In order to meet this demand, the power, density, and efficiency of server power supplies have been greatly improved. High-power server power modules require high-efficiency conversion and saving of power consumption. AC single-phase input, HVDC 400V input or increased DC voltage output designs can be utilized to achieve this purpose.
In order to ensure power stability when high-power servers are operating, power modules with hot-swappable redundant power supply specifications (such as CRPS) have been widely applied in server racks. Power modules with redundant functions require testing of multiple power modules at a time to ensure that all modules can maintain normal operation during high power output. Due to the rapid changes in the development of server power supplies, GW Instek developed the brand-new flagship model ASR-6000 series to meet customer needs.
The ASR-6000 series has two models — ASR-6450 AC / DC 4.5kVA and ASR-6600 AC / DC 6kVA
ASR-6000 is the first stand-alone unit from GW Instek that supports AC single/three-phase input and output, and has rated DC power output. The series employs third-generation semiconductor silicon carbide (SiC) technology to create a 4U 6kVA high power density and high-performance AC /DC power source.
ASR-6000 has the ability to emulate more diverse power environment changes, such as balanced and unbalanced three-phase, phase loss, and features multichannel output function can test up to three DUTs at the same time, programmable output impedance adjustment, and built-in over 40 types of arbitrary waveform outputs. The invincible launch of GW Instek flagship model ASR-6000 demonstrates that GW Instek can provide a complete test solution for high-power AC sources. ASR-6000 is the MVP of GW Instek power sources.
