New Taipei City, Taiwan – [2025/09/30] – GW Instek, a leading global manufacturer of electronic test and measurement instruments, proudly announces the expansion of its acclaimed AC/DC power source family with the introduction of the ASR-6000 series, featuring two new high-power models: ASR-6500 (5 kVA) and ASR-6660 (6.6 kVA). ___________________________________________________________________________________________________________

High Power Density with Next-Generation SiC Technology

Leveraging advanced silicon carbide (SiC) compound semiconductor technology, the ASR-6000 series achieves 4U 6.6 kVA high power density in a compact form factor. These new models support three-phase three-wire and three-phase four-wire AC input, while delivering both AC single-phase and three-phase output.

This technological breakthrough enables engineers to emulate a wide range of power environments – from balanced and unbalanced three-phase scenarios to phase-failure conditions – making the ASR-6000 series a versatile solution for demanding power testing applications. 

From 5 kVA to 6.6 kVA: Meeting the Rising Demands of AI Servers

The ASR-6000 series is specifically designed for high-power testing requirements, including server power modules with CRPS redundant functions.

• The ASR-3000 series remains a reliable solution for power testing up to 5 kVA. However, for higher-capacity needs, the ASR-6000 provides a powerful standalone alternative, eliminating the need to configure multiple units to achieve three-phase output.

• Customers seeking 5 kVA and above can now perform comprehensive single-phase or three-phase power testing with one unit, significantly streamlining test setups and improving operational efficiency. This advancement makes the ASR-6000 series particularly well-suited for next-generation AI servers and data centre power systems, where reliability and scalability are paramount. 

Comprehensive Features for Flexible Test Environments

The ASR-6000 series incorporates 10 versatile output modes, including mains synchronization (SYNC) and external voltage-controlled amplifier (VCA) output. With its multi-channel output function, engineers can replicate complex test conditions efficiently.

Key specifications include:

• AC Input: Three-phase only, 380 V to 415 V ±10 %

• AC Max Output: Phase voltage 350 Vrms / Line voltage 700 Vrms

• Frequency Range:

o AC Mode: 15.00 Hz to 2000.0 Hz

o AC+DC Mode: 1.00 Hz to 2000.0 Hz (standalone)

o Parallel Rack Type: up to 39.6 kVA, frequency de-rated

• Output Functions: Balanced/unbalanced three-phase, phase loss, programmable output impedance

• Waveform Control: Arbitrary waveform editing with tens of thousands of waveforms, sequence editing, and emulation output

• Monitoring & Measurement: Dual-channel voltage/current monitoring, harmonic analysis up to the 100th order

• Scalability: Parallel connection up to 39.6 kVA / 39.6 kW

• Control Interfaces: RS-232C, USB, LAN (standard); CAN Bus, DeviceNet, GPIB (optional)

• Web Server Support: Built-in web server for advanced remote control and data acquisition 

ASR-6000 vs. ASR-3000: A Clear Step Forward

While the ASR-3000 series supports three-phase output via multi-unit configuration, the ASR-6000 provides integrated three-phase power capability in a single unit, ensuring simpler setups, reduced space requirements, and increased efficiency for high-power applications.

This makes the ASR-6000 a future-ready solution for industries where power demands continue to escalate, such as AI data centres, semiconductor testing, renewable energy, and advanced power electronics. 

Commitment to Innovation and Reliability

The launch of the ASR-6000 series reinforces GW Instek’s dedication to delivering cutting-edge, reliable, and flexible test solutions that meet the evolving challenges of modern electronics and power system design. With the ASR-6500 and ASR-6660, engineers gain a powerful, high-density AC/DC source designed to enhance productivity, ensure accuracy, and accelerate development in high-power applications.
