220V 3500W Power Amplifier EMI Power Filter Soft Start Integrated Board with Temperature Protection Circuit Amplifier Board

220V 3500W Power Amplifier EMI Power Filter Soft Start Integrated Board with Temperature Protection Circuit Amplifier Board

Explain:

The princle of the power filter is one kind-impedance adaptation network: the greater the impedance mismatch between the input and output side of the power filter and the power supply and load side, the more effective the attenuation of electromagnetic interference. The soft start line is composed of high-power relays. It is composed of high-power thermistor, low-power backup power supply and control part. The board has two sets of 220V output, which can be easily connected to two independent s. This board is equped with a temperature protection circuit. Two temperature switches of 75 degrees are provided with the board. The two temperature switches can be installed on the surface of the heat sink or power tube of the left and right channels respectively. When the temperature reaches 75 degrees, the main power supply will be automatically cut off. In order to avoid the power amplifier tube from being burnt out due to exceively high temperature, if you need to change the shutdown temperature, you can purchase a normally open temperature switch with other temperature values. In addition, after the protection circuit is activated, it may be neceary to wait for a period of time until the actual temperature is lower than the start temperature of the temperature control switch before turning on the machine again.

Features:

1. High-power thermistor.

2. Filter soft start integrated board.

3. Two 75 degree temperature switches are included with the board.

4. This sub-board integrates high-power soft-start and filtering in one.

5. The power board adopts 1.6MM double-sided tinned board, supporting power within 3500W

6. The power supply is divided into self-locking switch or self-reset switch (need to be purchased by yourself).

7.The board has two sets of 220V outputs, which can be easily connected to two independent s.
