About this product
Product information from the supplier.
An Isolation Transformer is a critical power component engineered to decouple a device from the power source. By utilizing two or more independent windings wrapped around a high-grade iron core without a direct electrical connection, these transformers create a galvanically isolated circuit. This structure is essential for protecting sensitive electronic equipment and personnel from electrical shocks and hazardous voltage surges.
Operating on the principle of electromagnetic induction, an alternating current applied to the primary winding generates a magnetic field within the iron core, which subsequently induces an electromotive force in the secondary winding. This sophisticated mechanism not only enables precise voltage transformation but also serves as a robust filter that effectively blocks direct-current (DC) offsets and low-frequency noise, ensuring a clean and stable power supply for industrial applications.

Frequently Asked Questions
Q: What is the primary purpose of an isolation transformer?
The primary purpose is to decouple the electrical load from the power source, enhancing safety by preventing electric shocks and protecting sensitive equipment from electrical noise and DC offsets.
Q: How does an isolation transformer block noise?
Since there is no direct physical electrical connection between the primary and secondary windings, DC and low-frequency noise cannot cross the gap, only the alternating magnetic field transfers energy.
Q: Is an isolation transformer the same as a voltage stabilizer?
No. While both manage power, an isolation transformer focuses on electrical separation and noise filtration, whereas a voltage stabilizer actively regulates fluctuating input voltage to a constant output.
Q: Can isolation transformers be used in medical environments?
Yes, they are highly recommended in medical settings to isolate patients and sensitive monitoring equipment from the mains power, reducing leakage currents.
Q: What is the difference between oil-immersed and dry-type isolation transformers?
Oil-immersed transformers use oil for cooling and insulation, making them ideal for high-power outdoor use, while dry-type units use air, making them safer for indoor installations.
Q: How do I choose the correct kVA rating for my isolation transformer?
You should calculate the total wattage of all connected devices and add a safety margin of 20-30% to ensure the transformer operates efficiently without overheating.
