Usage Tips:Thanks to the full soldering of the enamelled wire to the electric wire, which prevents desoldering, and the insulating sleeves which increase the insulation performance, it provides secure handling. Boasting wide voltage ranges and multiple input supply solutions, the power transformers are more stable, with precise voltage and current and high efficiency. Made of high-quality plastic, metal and copper core, the power transformer ensure safe operation. The length of the power transformer is 29mm, the width is 13mm and the height is 26mm. The input and output lead are both 13cm long, and the mounting hole is 42mm. It can be used for home security, household appliances, machinery, and industrial equipment, etc. Item Name: Power Transformer Material: Copper,Plastic, Metal Power: 1W Frequency: 50-60Hz Input: AC 220V 50Hz Specification: EI 28x12 Output Voltage: 6/9/12/18/24V Phase Type: Single Phase Isolation Features: Safe Protection, Heat Resistant, Insulated Size Details: Power Transformer Size: 29mm x 13mm x 26mm/1.14" x 0.51" x 1.02" (Approx.)
