UWAAmplifier
WONDOM
PEMFAmp

WONDOM High Power Dual Power Supply Series is a highly efficient and highly reliable series based on high performance IRS2092 chip, power ranging from 500W to 3000W. The entire series is equipped with complete protection circuit and supports flexible load characteristic and wide load range. Supporting wide frequency range is another highlight of this series.

Flexible Load Characteristic

Electronical appliances can be divided into resistive load, inductive load and capacitive load. It’s easy for amplifiers to drive resistive load such as the speakers. Since the impedance of the inductive load and capacitive load would change with frequency and there will be reactive power when driving both inductive and capacitive load, it raises high requirements of the amplifiers.

WONDOM high power dual power supply series can handle with inductive load and capacitive load. However, extra attention should be paid for any operation with purely capacitive loads. For any non-audio applications, customers are suggested to send an inquiry e-mail to Sure Electronics for system compatibility confirmation or face the consequences.

Wide Load Range

With its low output impedance, the entire series supports wide load range, showing stable performance with 1Ω without impact by loudspeakers loading characteristics. Therefore, the high power dual power supply series is capable of standing and dealing with high current.

Wide Frequency Range

Audio frequency range is 20Hz-20kHz. Thanks to our exquisite PCB layout design and the special technology employed in our amplifier, the high power dual power supply series can handle with wide bandwidth from 10Hz to 22kHz with uncompromising frequency response, not only meeting requirements of audio system but also satisfying special demands of some applications such as Physical Therapy Machines, Underwater Acoustics and so on.

This series is able to support extremely wide frequency range as 5Hz-80kHz through some configurations. If you have any need, please contact us.

High Output Voltage

The maximum output voltage of WONDOM IRS2092 series can reach 200V÷2.828≈70.72V>70V in half bridge structure. And it can deliver 200V÷1.414≈141.44V in full bridge structure.

Another series of amplifiers that can deliver 280V RMS output voltage will be released soon, so stay tuned.

DISCLIMER

WONDOM standard products can only be used in audio applications and there is a big difference between the standard products and the specialized version on protection and performance. If you have any requirement on non-audio applications, please contact us to get the products specially optimized for specific applications.

Video

In this video, we will use WONDOM 1 X 2500WATT CLASS D AUDIO AMPLIFIER BOARD - IRS2092 (AA-AB31491) to drive the air conditioner. The video of frequency range testing, driving electronical stove and driving the coil to heat up water and the video of actually showing 2500W RMS power have been uploaded to our YouTube channel.
