CAT III 1000 V
Key Features

• The ideal current sensor for measuring large1000 A currents in EV, HEV, and PHEV
• Strengthened shield improves noise resistance to accurately measure current buried in noise
• Flat frequency characteristics and CMRR performance to achieve high accuracy measurement
• More enhanced environmental resistance performance than ever before with operating temperature range of -40 to 85°C
• Basic accuracy of ± 0.04% and phase ± 0.1°
• Good frequency characteristics over wide band of DC to 1.5 MHz (amplitude) and DC to 1 MHz (phase)
• Ideal for advanced fields such as photovoltaics and fuel cells to evaluate the charge / discharge of batteries and secondary side of inverters
• Connect with oscilloscopes or Hioki Memory HiCorders (using SENSOR UNIT) to monitor waveforms
