The LA 25-NP is produced by a leading company in a electrical measurement called Life Energy Motion (LEM). The LA 25-NP is a current transducer. Which is also used for the electronic measurement of (pulsed, mixed, DC, AC)  current, carried out with galvanic separation between the primary and the secondary circuit of the LA 25-NP. This electronic module gives out instant output, excellent accuracy, fast response time, wide frequency bandwidth, no insertion losses, and current overload capability.


  • Closed loop (compensated) multi-range current transducer using the Hall Effect technology.

The LA 25-NP is a current transducer that looks and functions similar to a current transformer. This day, you can find the LA 25-NP more in industries where they are concern about monitoring the motor or heater loads for instance. The LA 25-NP has built-in circuitry that generates a low-level DC signal base on the level of AC amps. This signal is usually an analog (0-5VDC), (0-10VDC), or (4-20ma) and will most times be a pulsed output where the frequency of the pulse output is proportional to the amps going in through the LA 25-NP

  • Servo motor drives and AC variable speed drives are one of its main use.
  • They are used in static converters for DC motor drives.
  • Battery supplied applications also use it.
  • It can be used to create uninterruptible Power Supplies (UPS).
  • Switched Mode Power Supplies (SMPS).
  • A form of power supplies for welding applications.
