SANO三锘智能型伺服變壓器是三锘(SANO)公司2000年引進的一種小型伺服變壓器，該產品是專門針對中國電網與伺服系統所需電壓不匹配而設計的超小體積三相伺服變壓器。改變了現傳統線圈式變壓器的笨重、發熱、耗電、安裝難等問題；不對電網造成污染，是工業控制系統中解決電源適配器問題的理想產品，與工頻變壓器有本質上的不同，在性能上有質的飛躍。
        SANO Intelligent Servo Transformer is one kind of mini servo transformer introduced since year 2000. It is super-mini specialized servo transformer, spe-cialized to the non-match of the voltages between China electrical mesh and AC servo motor. Such mini transformer has overcome the disadvantage of the traditional transformer: heavy, heating, high energy consumption, complex installation etc, which, totally different from the industrial frequency transformer, is the ideal product for solving the power adaptor in industrial controlling field, without any pollution to the electrical mesh.
