Feature: The product is made of high quality silicon steel sheet with low eddy current loss. The coil adopts all-copper varnished wire, which has good conductivity and long service life. The assistant accessories of product : nylon flame retardant rubber core, flame retardant tape, high temperature resistant lead, and the product is safer to use. The product as a whole is strictly insulated and its safety is guaranteed. Products support a variety of cooling methods, more convenient to use. Specification: Product Name: Isolation Transformer Core type : EI48*24 Rated power: 12W Input voltage: 220V Frequency: 50Hz Output voltage: 24V Frequency characteristics: low frequency Core shape: EI type Moisture proof method: open type Cooling method: natural cooling Cooling form: liquid / oil immersion Structure: Isolation transformer Coil material: copper enameled wire Two-level linearity: red line initial input blue line secondary output Length of each line: Input line length 130mm Output line length 130mm Package list: 1 * Power Transformer Note: The rated voltage of transformer is made according to the load voltage. When no-load measuring, the voltage will show about 10% higher, which belongs to the normal phenomenon. After loading, it will all drop to the rated voltage. Buyers are assured to use it. The actual product color may deviate from the photo due to light. There may be a slight deviation in the measurement of product.
