Monitoring the phase current of motors and BUS voltage fluctuations for accurate feedback to the microcontroller is essential to realizing the high-precision operation required in recent industrial equipment, including inverters and servo amplifiers. In order to meet these requirements, the new optical coupled isolation amplifiers are equipped with a high-precision delta-sigma AD converter on the input side and achieve the industry’s highest level of linearity[1], a performance of 0.02%(typ.)@NL200 for the analog output products and 3LSB(typ.)@INL for the digital output products. The isolation amplifiers also secure a CMTI (Common-Mode Transient Immunity) value of 20kV/μs(typ.), enabling stable operation in motor control applications which usually generate high levels of noise. Furthermore, the 5000V(min.) isolation voltage makes them suitable for use in various industrial equipment applications.

 

Applications:

 

  1. Industrial equipment including inverters, servo amplifiers, robots, CNCs and power supplies
  2. Wind turbine and photovoltaic inverters, battery management
  3. UPS, power supplies for servers, battery management and air-conditioners for office and residential use
