Introduction:- Audiophiles extensively use ring transformers in electronic products such as audio amplifiers. The magnetic permeability of the ring transformer core is high, and a lower number of turns per volt can be used in transformer design. The internal resistance of the transformer is also low, and the leakage flux is also minimal, resulting in excellent performance. However, such high permeability and low leakage cores also have some drawbacks, especially when the electromagnetic waveform is asymmetric or contains DC components, which can easily cause magnetic saturation in the transformer core. This will directly lead to a reduction in the working range of the transformer core, and the intuitive feeling is the generation of AC humming sounds. In fact, even if the DC component is as low as only 1-2V, it can cause a noticeable ringing of the transformer.
- It can effectively eliminate the DC component in AC power, and by suppressing the DC component in AC power, the transformer can operate in a relatively ideal working state. This is very effective in suppressing transformer noise caused by DC components in AC power. After connecting this product, the transformer will become very quiet.

FAQ:Q: What is the function of DC power filter?
A: Eliminate transformer hum: solve the problem of transformer noise caused by the presence of DC components in the power grid.
Protecting precision equipment: isolating power grid pollution, extending the lifespan of industrial instruments such as amplifiers and recording equipment.
Real time status monitoring: LED indicator lights intuitively reflect the health of the power grid.
Q: Which devices are applicable?
A: Suitable for equipment with high power quality requirements such as power amplifiers, speakers, recording equipment, industrial motors, medical instruments, etc.
Q: What should I do if the LED indicator light is on?
A: The red light indicates the presence of a high DC component in the power grid, even if the DC component is only 1-2V, it can clearly trigger the sound of a faulty transformer.
Q: How to install it?
A: No installation required, plug and play.
