DC Filter Amplifier Interference Suppression Board Class D

This board adopts the working principle of LC differential common mode, which can suppress the interference of switching power supply or other DC power supply, reduce the ripple of power supply, reduce the interference caused by a power supply, can be used for low-voltage DC (0~50V) power supply circuit, such as power amplifier board, vehicle equipment, industrial control board, DC electrical appliances and so on. The use of the circuit is flexible when the suppression effect is not up to the requirements, can be multi-level series, enhancing the suppression ability, when the working current of the board is not up to the demand, can be multiple parallels, increase the output current, for the use of positive and negative power supply circuit board can be two superposition, composed of positive and negative power interference suppression board. The board is divided into two voltage specifications, 0~25V, and 0~50V, according to the range of working voltage that can be selected to match the filter board.

This Filter Board adopts the principle of the common differential mode lc, which can suppress interference in the switching power supply or other dc power supply.

Reduce the ripple of the power supply, and reduce the interference brought by the power supply.
Can be used in low voltage (0 v 50 50 v) dc power supply circuits, such as power amplifier boards, vehicle equipment, industrial control board, dc electrical appliances, etc.

The circuit is flexible to use. When the suppression effect does not meet the requirements, it can be connected in series on several levels to increase the inhibiting capacity.

When the working current of the Filter Board does not meet the requirements, it can be connected in parallel with several blocks to increase the output current.

For the circuit board using a positive and negative power supply, two blocks can be overlapped to form a positive and negative energy interference suppression board.

The board can be divided into two voltage specifications, 0 25 25 v, and 0 50 50 v. The combined filter plate can be selected according to the working voltage range used.

The current of the TPA3116 machine makes the energy input pure, so the amplifier is less noisy. You will receive less humming sound in your amplifier or it may remove humming in audio completely.
