The WISO Isolation Amplifier series are analog signal isolation devices developed by Startorus Fusion for fusion plasma experiment applications and similar scenarios. The isolation amplifiers support ±5V input with a bandwidth of DC to 100 kHz and an isolation voltage of up to 3000 VDC. Their 1 MΩ input impedance minimizes errors introduced by the signal source internal resistance, and an internal low-pass filter is designed to suppress output signal noise. The product line offers both 1U and 4U chassis configurations, supporting PCI-1720U and PCI-1713U interfaces respectively, to meet diverse channel requirement scenarios.

The WISO Isolation Amplifier series is primarily designed for fusion plasma experimental scenarios, suitable for analog signal acquisition and isolation in high-voltage environments such as Tokamak devices and magnetically confined fusion experimental platforms. The 3000 VDC isolation withstand voltage effectively protects downstream acquisition equipment from strong electromagnetic interference (EMI) and high common-mode voltage transients.
The WISO224-4-1U features a compact design and supports direct interfacing with the PCI-1720U data acquisition card, facilitating flexible deployment within the experimental control room rack, making it ideal for applications with limited channel requirements or space constraints.
The WISO224-32-4U integrates 32 channels into a standard chassis with support for direct interfacing with the PCI-1713U data acquisition card, well-suited for large-scale rack-mounted integration in experimental control rooms.
Additionally, this product line is widely applicable to other scientific and industrial measurement and control scenarios requiring high isolation and wide-bandwidth analog signal transmission, such as high-voltage pulsed power supply monitoring and precision sensor signal conditioning.
