• Three-Phase Current Monitoring

    Sep 17, 2019
    A custom industrial furnace manufacturer came to OSI for three-phase current monitoring on a furnace. Ohio Semitronics supplied a split-core CTY series Current Transformer (UL listed) in combination with the 3ACT Three-Phase AC Current Transducer, also UL listed, which provides three isolated dc outputs that are directly proportional to the three current inputs.

  • Nano Technology Experiments Require "Quiet" Grounding

    Jul 29, 2019
    A major research university asked OSI to deliver AC measurements to meet their needs for experimenting and requested resolution to 0.25 mA or 250 µA. Not challenging in itself, but the measurement device must also withstand a 20-amp surge in fault conditions. That’s a withstand range of 8 x 105 while maintaining the original accuracy when returned to the normal operating conditions. READ MORE
