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 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 three-phase and unbalanced three-phase, phase loss, and features a multi-channel output function that 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 ASR-6000 series consists of 2 models, the ASR-6450 and ASR6600, differing in capacity.

The Instek ASR-6000 provides more than 40 built-in waveforms, including: TRI, STAIR, CLIP, CF-1, CF2, SURGE, DST01-22, RIPPLE, DIP, LF-RING. Each waveform also provides a change setting function, which can modulate thousands of combined waveforms and quickly emulate different AC output environments.

Users can adjust the required waveform type through the panel (the screen is displayed simultaneously), then load it into the ARB 1~16 waveform register through the access step and return to the main menu output mode to perform ARB Waveform output. Users can also edit waveform through ASR-6000 software and then import it into ASR-6000 for execution.

The ASR-6000 series has diverse output functions, including three modes: 1P2W, 1P3W, and 3P4W. The maximum output for phase voltage is 350Vrms and the maximum output for line voltage is 700Vrms. In AC three-phase output (3P4W) mode, each phase supports independent output settings. Taking ASR-6600 as an example, the maximum output of each phase reaches 2kVA, supporting power supply testing of up to three DUTs to meet the needs of server power modules. Testing requirements for high-power AC power products such as electric vehicle chargers and uninterruptible power supply systems.

• The ASR-6000 series has unbalanced and balanced three-phase output modes. In the AC three-phase output mode, users can set the phase angles of L1, L2, and L3 for control.
• Main applications: Three-phase input power supply products, when emulating unbalanced three-phase input and phase loss, the ability of three-phase power input products to restore balanced three-phase.

• In order to meet the test requirements of different DUT output voltages, it is necessary to adjust the rise time of different output voltages. The ASR-6000 offers users up to three adjustable settings: typical values are fast (50 microseconds), medium (100 microseconds), and slow (300 microseconds). ASR-6000 is initially set to medium speed.
• Application: It can output high-speed arbitrary waveforms to emulate various changes in the power system caused by transient high-speed rising voltage, etc.

A high-performance AC power source = amplifier + signal source. It has: internal output + external input signal to control internal output + amplify external input signal and output, and other diversified output functions. ASR-6000 has up to 10 output modes.
