Product Description
XISAOK 100A 4000W High-Power Soft Start Circuit Power Board for Class A Amplifier Amp High Power Soft Start Circuit Board
About This Item
Introducing the XISAOK 100A 4000W High-Power Soft Start Circuit Power Board for Class A Amplifier Amp. Are you tired of the instantaneous impact current that can damage your amplifier and shorten its lifespan? The XISAOK High-Power Soft Start Circuit Power Board is the perfect solution to reduce the impact on the grid and protect your valuable equipment. Featuring an ultra-high current (100A) pure copper foot relay and an oversized thermistor NTC 20D-20, this power board effectively shields your amplifier from excessive startup current. With this soft start circuit board, you can enjoy longer-lasting and reliable performance. One of the best things about this soft start circuit board is its easy installation. It doesn't require an auxiliary power supply, making it incredibly convenient to use.
Simply connect the power input and the output load, and you're good to go. You can even connect a switch for added control. The working principle of this power board is simple yet effective. When you turn on the power supply, the thermistor regulates the load power supply.
As the temperature of the thermistor increases, the resistance decreases, and the voltage rises slowly. This helps suppress surge current and prevent any damage to the electrical components. The XISAOK High-Power Soft Start Circuit Power Board is not only suitable for high-end audio power input but also for other appliances with large startup currents. With a power rating of up to 4000W, this board can handle even the most demanding applications. Measuring approximately 6.2x6.1cm, this power board is compact and easy to integrate into your setup.
It is designed for AC power supplies ranging from 150V to 280V, providing versatility for different environments. Please note that there may be a slight measurement error of 1-3mm due to manual measurement. Additionally, the actual color of the item may vary slightly from the images due to monitor differences. With the XISAOK High-Power Soft Start Circuit Power Board, you can protect your equipment, prolong its lifespan, and ensure smooth and reliable operation. Don't settle for anything less when it comes to the performance and longevity of your amplifier. Order your XISAOK High-Power Soft Start Circuit Power Board today and experience the difference it can make to your audio setup or any other high-power applications.

Customer Questions & Answers
-
Question:
What is the purpose of the XISAOK 100A 4000W Soft Start Circuit Power Board?
Answer: The primary purpose of the XISAOK 100A 4000W Soft Start Circuit Power Board is to provide a gentle power-on sequence for high-power Class A amplifiers. This soft start feature helps reduce inrush current, which can lead to system failures and damage. By gradually ramping up the voltage, the circuit board ensures a smoother operation, allowing amplifiers to perform optimally without abrupt power demands. This is particularly beneficial in high-fidelity audio systems where equipment longevity and sound quality are paramount. -
Question:
How does the soft start feature benefit my amplifier?
Answer: The soft start feature significantly benefits your amplifier by minimizing the stress on both the electrical components and the power supply. When an amplifier powers on, a sudden surge of current can cause voltage spikes; this may damage sensitive electronics. The XISAOK board mitigates these risks by controlling the initial power flow, which not only enhances reliability but also provides a more stable audio performance, especially in professional and home audio settings where every detail matters. -
Question:
Can the XISAOK circuit board handle other electronic devices?
Answer: While the XISAOK 100A 4000W Soft Start Circuit is designed primarily for Class A amplifiers, it can also be utilized with other high-power electronics that require a soft start to prevent inrush current. Devices like large speakers or subwoofers that draw significant power can benefit from this type of circuit. It’s essential, however, to evaluate the device's compatibility with the voltage and current ratings to ensure safety and efficiency. -
Question:
What is the maximum current and power handling capacity of this circuit board?
Answer: The XISAOK Soft Start Circuit can handle a maximum current of 100A and power up to 4000W, making it suitable for high-performance applications. This impressive capacity is ideal for driving large Class A amplifiers that require substantial power. Users in the audio production or high-end audio enthusiast space will find this capability essential for maintaining sound quality while ensuring that their equipment operates within safe parameters. -
