That single-phase transformer primary winding and a secondary winding of the transformer are single-phase winding. Simple structure, small size, low loss, mainly iron loss is small, suitable for smaller load density low-voltage distribution grid application and promotion. Real Tuoudepu single-phase transformer power transformer (single-phase transformer) Description of the product to achieve conversion 110v / 120v / 240v AC power through the AC voltage between the conversion, easy to carry you use in the United States, Canada, Japan and other countries of the electrical environment rated voltage 220v appliances, but also facilitate you to use to carry the rated voltage of 110v electrical products in China, Germany and other countries electricity environment 220v / 240v's. Please read carefully before using this manual single-phase transformer! As losses due to failure to use due to the specification, the Company does not assume corresponding responsibility. Voltage product identification must be entered consistent with the local power supply voltage to avoid damage to electrical appliances. Load power must not exceed the rated power transformer. This product can only be used indoors, not exposed to the weather.
