Increasingly high levels of efficiency and precision are desired in power systems and storage systems in recent years.
Current sensors offer the advantage of being able to conduct measurements while totally insulating the primary side from the secondary side.
At the same time, there is an issue in that precision can be adversely affected by fluctuations in whole elements and temperature characteristics.
TOYO SYSTEM leverages the technologies and experience it has nurtured in charge-discharge test systems and battery packs, to design and manufacture the current sensors that meets customer demands
This sensor incorporates unique temperature correcting technology for minimizing the impact of temperature characteristics of whole elements on precision. This sensor proves especially effective in applications where changes in the environmental temperature are large.
Through passing current in the direction that negates the magnetic field generated by the primary current, this sensor can measure with a higher degree of precision than the magnetic proportion system. Similar to the magnetic proportion system, it is effective when used for purposes amidst large temperature changes.
This ultra-high-precision current sensor uses high sensitivity magnetic susceptibility elements. This sensor is equipped with a unique self prevention circuit to avoid any circuit destruction etc. due to sensor disturbance. It has temperature characteristics of 0.05ppm/K, which is the top in industry.
