Current Sensors

Despite its small package size, Currentier insulation complies with UL61800-5-1 levels. Currentiers also generate less heat, are fast response, and achieve high accuracy. We offer an extensive lineup of Currentier product series, each with its own strengths.

In this section, we introduce some examples of using Currentiers to solve problems as well as recommendations for individual products so that you choose the product that meets your application needs.

Typical applications

  • AC servo / General Inverter (Drives) / Multi-axis robot for Industry
  • Photovoltaic Inverter
  • Stepper Motors
  • Switched-Mode Power Supply
  • Charging Station
  • UPS (Uninterruptible Power Supply)
  • Smart Factory

You can find more details below. You can use it for many other purposes as well.

AC servo / General Inverter (Drives) for Industry

In the application of AC servo and general inverter for industrial machinary, current sensors are used in following three places;

  1. Power Factor Correction (PFC)
  2. Vector control
  3. Over current detection


In this page, we would like to propose you our recommendation of AKM products in each place with its superiority.

Photovoltaic Inverter

In the application of photovoltaic inverter (PV inverter), current sensor are used infollowing two places;

  1. DC Current Detecting
  2. AC Current Detecting


In this page, we would like to propose you our recommendation of AKM products in each place with its superiority.
