IWATSU Electric Co., Ltd. products

The SY-8218 and SY-8219 devices are specialized for measuring the AC magnetic properties of soft magnetic materials. Ideal for use in research and development, quality assurance, and manufacturing, these devices support precise evaluation of material, core, parts, and equipment magnetic characteristics. The units facilitate comprehensive measurements, including BH curve, power loss (Pc), permeability (m), inductance (L), and quality factor (Q). Their application spans a variety of industries where magnetic component performance validation is critical. These devices are designed to support new product development and inspection, offering reliable solutions for accurately gauging the magnetic behavior under AC conditions.

The Isolation System DM-8000H is designed specifically to enhance the accuracy and safety of inverter voltage measurements, including Vce and Vge of the inverter's upper arms. Traditional single-ended oscilloscope probes pose significant risks, and although differential probes are an alternative, they suffer from various limitations such as in-phase removal ratio and voltage resistance issues, which lead to waveform distortion and inadequate measurement bandwidth. The DM-8000H addresses these challenges by incorporating an isolation method utilizing optical fibers and battery power, thereby circumventing conventional constraints. This system enables simultaneous measurement of upper and lower arm parameters like Vce, Vge, Ic, output voltage, and current waveforms. Additionally, it allows for measuring crucial parameters such as dv/dt, di/dt, and power loss. It also supports long-distance, multi-point surge measurements, capable of extending optical fiber cable up to 200 meters for distant evaluations.
