High Power Amplifier for Acoustic Transducer

In summary, the conversation is about someone looking for a power amplifier that can output 340 Vrms across a 25 ohm impedance load with specific requirements for pulsed mode, duty cycle, pulse length, and operating frequency. They are seeking recommendations for COTs power amplifiers and have been directed to a Google search result for 5kW AM transmitters. The person asking for recommendations also mentions their background and experience with working with high voltages and ultrasound.

Hi all

I am in search of a Power Amplifier (preferably Solid state pulsed amplifier ) which is able to output around 340 Vrms across 25 ohm impedance load (acoustic transducer operating at approx 4.5 KW) in pulsed mode with duty cycle less than 1%, maximum pulse length of 5 ms and operating frequency is in range of 400-500 KHz.

If anyone knows about COTs power amplifiers meeting these requirements, kindly share with me.

Thanks & Regards
Nauman

What is the application? What is your background working with voltages over SELV? What is your experience working with ultrasound at those power levels?...

1. What is a high power amplifier for acoustic transducer?

A high power amplifier for acoustic transducer is an electronic device that is designed to amplify the output signal of an acoustic transducer, such as a microphone or speaker. It is used to increase the power and volume of the acoustic signal, allowing it to be heard or recorded more easily.

2. How does a high power amplifier for acoustic transducer work?

A high power amplifier for acoustic transducer works by taking the electrical signal from the acoustic transducer and increasing its power using electronic components such as transistors and capacitors. The amplified signal is then sent to a speaker or other output device to produce a louder and clearer sound.

3. What are the benefits of using a high power amplifier for acoustic transducer?

The main benefit of using a high power amplifier for acoustic transducer is that it allows for a stronger and more clear signal to be produced. This is especially useful in large venues or outdoor settings where the sound needs to reach a larger audience. It also reduces distortion and improves the overall quality of the sound.

4. What are some common applications of high power amplifiers for acoustic transducers?

High power amplifiers for acoustic transducers are commonly used in live music performances, public address systems, and recording studios. They are also used in home stereo systems and car audio systems to improve the sound quality and volume.

5. Are there any safety precautions to consider when using a high power amplifier for acoustic transducer?

Yes, it is important to follow the manufacturer's instructions and guidelines when using a high power amplifier for acoustic transducer. Make sure to properly ground the amplifier and use appropriate power sources to avoid electrical hazards. It is also important to monitor the heat generated by the amplifier and ensure proper ventilation to prevent overheating.
