雙電壓110V/220V 設備專用。PP馬達式穩壓器主變壓器採環型線圈，適用範圍廣、省電、效率高，雙用電壓機型，輸入輸出均有110V/220V可用，小容量負載穩壓變壓一次完成，工程設計師及老闆最愛機種。
Special for dual voltage 110V / 220V equipment. The main transformer of the PP motor-type voltage regulator adopts a ring-shaped coil, which has a wide range of applications, power saving, and high efficiency. It is a dual-use voltage model with both input and output 110V / 220V available. The small-capacity load voltage stabilization and transformation can be completed in one operation. Engineering design Division and boss favorite models.
