Can a buck-boost transformer be used as an isolating transformer for low voltage control circuit?

A buck-boost transformer is primarily designed to adjust voltage levels in a specific range, typically used to raise or lower voltage for particular applications, such as lighting systems or small machines. While it can provide some level of isolation between the primary and secondary circuits, it does not meet the full criteria required to be classified as a true isolating transformer for low voltage control circuits.

Isolating transformers serve the essential purpose of providing electrical isolation, which is crucial for the safety and protection of low voltage control circuits. These transformers are designed to provide galvanic isolation, preventing ground loops and ensuring that fault currents do not pass through sensitive areas of a circuit.

Thus, while a buck-boost transformer can be utilized in certain scenarios, it does not fulfill all the necessary requirements to adequately isolate control circuits from the primary line voltage. Hence, it is not suitable for use as an isolating transformer in low voltage applications.
