289 Series, Isolation Transformers and Autotransformers, Step Up, Step Down

The products within this category are intended to be used in conjunction with AC utility power for various safety or functional purposes. Two common types of transformers in this family are isolation transformers and autotransformers. Isolation transformers are specifically designed to transfer electrical power from one circuit to another without establishing a direct electrical connection. They provide galvanic isolation, which means they prevent the flow of electric current between the input and output circuits. Isolation transformers are frequently utilized in repair or product development environments where the mitigation of shock hazards is crucial. By isolating the circuits, these transformers ensure that any potential electrical faults or leakage currents do not pose a risk to the user, thereby enhancing overall safety. On the other hand, autotransformers are used for voltage scaling purposes. They can increase or decrease the voltage of an available power source to meet specific functional requirements. Unlike isolation transformers, autotransformers do not provide galvanic isolation between the input and output circuits. Therefore, they are employed when electrical isolation is not necessary. Autotransformers are commonly used in scenarios where voltage conversion is needed, such as stepping up or stepping down the voltage for specific equipment or devices. In summary, products within this category serve different purposes in relation to AC utility power. Isolation transformers are utilized to transfer electrical power without establishing a galvanic connection, ensuring safety by mitigating shock hazards. Autotransformers, on the other hand, are used to scale the voltage of an available source to meet functional requirements when isolation between input and output circuits is unnecessary.
