Glyn High-Tech Distribution is partnering with Tamura Corporation of Japan to offer Hall-Effect current sensors which are essential in various applications. Tamura Corporation is a world-class manufacturer of high quality electronic components for the global industrial, telecom and consumer markets and is one of the largest suppliers of magnetic components and power supplies in the world.
Hall Effect current sensors offer advantages over other current measuring methods such as DC shunts, AC transformers, and ‘home-made’ current sensors by providing a fully integrated current sensor able to measure AC, DC, and complex currents at a lower total implementation cost. Tamura’s Hall Effect current sensors can measure currents in DC, AC, and pulse waveforms while providing galvanic isolation, fast response, and zero insertion loss at competitive prices.
Typical applications for Hall Effect current sensors include:
● Variable speed drives
● Motion control
● Overcurrent protection
● Ground fault detectors
● Current feedback control systems
● UPS and telecommunication power supplies
● Welding power supplies
● Automotive - Battery management systems
There are two types of Hall Effect current sensors – Open Loop and Closed Loop. Open Loop Hall Effect current sensors with its output voltage proportional to the primary current are the right choice for many applications. Nonetheless, Open Loop sensors may not reach the linearity and gain requirements of some applications. Closed Loop current sensors offer higher accuracy by correcting the linearity and gain errors through a negative feedback. The output current of a Closed Loop current sensor is an exact representation of the primary current scaled by the number of turns in the secondary coil.
Tamura also have equivalent Hall Effect current sensors to those offered by its competitors such as LEM or Honeywell.
