Toyo Keiki
Toyo Keiki ALS-A Series AC Current Transducer Transducer
Product Made In Japan
Manufacturer: Toyo Keiki
Model: ALS-A Series
ALS-□A: Mean value type
ALS-□EA : Root-mean-square value type
It is lighter because plastic is used for casing.
Improved reliability and greater compactness through the use of custom ICs.
JIS c 1111 AC/DC transducer 0.5 class.
