Clever Use of Isolation Transformers to Make Power Supply Safer and More Reliable

Isolation transformers have extraordinary significance in the field of power supply applications to ensure the safety of electricity use. Output voltages higher than 36V will endanger life, so should we not isolate the power transformer if the output voltage is lower than 36V? No, in addition to voltage isolation and conversion, isolation transformers also have special applications for circuits.

For isolation transformers, the first thing we know is that they can perform voltage isolation to ensure the safety of electricity use. As a power transformer, the function of the isolation transformer is not just 1:1 voltage conversion. In order to meet the safe use of electricity for various electrical appliances, the isolation transformer has achieved the technical level of freely designing conversion voltage parameters.

In electronic circuits, there are many components and the circuits have strict requirements on various interferences. Using isolation transformers to isolate the interference of the mains to the circuit can prevent the transmission of some harmonics, and at the same time increase the impedance of the circuit system, making it easier for protection devices to cooperate. When a short-circuit accident occurs on the load side, the isolation transformer can also play a role in limiting the short-circuit current of the system.

EEIO isolation transformer is a type of toroidal transformer. It has outstanding advantages in small low-frequency transformers above 300W, that is, low temperature rise and low no-load loss. Power supplies that work for a long time get hot, such as mechanical equipment, and prefer to use isolation toroidal transformers as power transformers. For instruments and meters that have strict interference processing, the low leakage magnetic field and small interference of EEIO toroidal transformers are more in line with the requirements of instrument transformers. Clever use of isolation transformers makes the power supply safer and more reliable.
