However, special attention should be paid to any operation with purely capacitive loads. We have already optimized the frequency response of the load and the HPA series has been tested with capacitive loads and resistive loads like coil, electric oven and resistance to guarantee the stability and performance of the amplifier. With its low output impedance, the HPA series supports loads from 1.5Ω to 16Ω without impact from the charging characteristics of the speakers. Contact Sure Electronics at info ) for greater customization of the power supply range. Application customers can free development resources and significantly reduce installation time and system costs. For those customers who require more power, assorted boost boost converters and AC-DC power modules are also available in Sure Electronics, so it is possible to achieve 2kW power and audio resolution without any difficulty. For amplifiers, higher input voltage means more power. 48V switching power supplies are commonly used in industrial applications and will be sufficient to evaluate our amplifiers. Each model can be powered directly from the DC power supply. Taking full account of the power supply solution, the HPA series is designed based on the Class T modulator (a branch of Tripath Class-D). The HPA series allows a universal supply voltage range from DC48V to DC200V (for HPA1, the supply voltage range is DC48V - DC200V while for HPA2, the supply voltage range is DC48V - DC120V). Flexible load characteristics from 1.5Ω to 16Ω The amplifier can accept up to a maximum of 10VRMS signal input. The flexible input sensitivity makes the amplifier perfectly compatible with MP3, the professional preamplifier the amplifier can always offer the best solution for different types of audio sources and players. The input sensitivity of the HPA series can be adjusted over a very wide range. With exceptional features such as loop loops and component optimization during design and measurement, we are able to deliver better audio quality products, with a higher SNR and a lower THD + N. ![]() With over 10 years of experience in audio design, our specialized engineers ensure that our products always have a better layout than our competitors. ![]() The entire HPA series is driven by the Class-T modulator (a branch of the Tripath-D class) and the entire series provides a very warm and powerful sound. HPA is a highly reliable series of high power amplifiers that combines twelve high power amplifiers with a single power supply solution.
