Huntkey HKA06524027-6C 24V 2.5A 60W AC/DC Power Adapter




This mid-power mono audio amplifier board delivers 60W output power into a 4Ohm load based on Class D topology and TI’s TPA3118 chip, featuring low power consumption as 0.1W in standby mode and high efficiency up to 95%. Compact size, easy installation and mid-power output makes this audio amplifier board suitable for home audio, DIY audio, toy audio and demanding industrial applications. A DC10V – 26V power supply is required.

High Quality Audio Performance

By means of dedicated PCB layout design and engineers’ attentive debugging, this low power audio amplifier board features high audio performance, whose SNR reaches up to 101dB and THD+N performs well as 0.062% @ 4Ohm, 1W, 1kHz.

High Reliability and Long Service Time

Excellent heat dissipation eliminates the requirement of an extra heatsink and increases its reliability. Full protection circuit, like over temperature protection and overcurrent protection, is equipped on this board for high reliability and long service time.

Easy for Installation

Four screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. Essential terminal interfaces for normal use are pre-mounted on the board, all you need to do is to plug in cables for connection, without any demand of soldering, which is swift and convenient. If you want all the interfaces, please contact us. MOQ would be required. Power indicator is provided on board for customers to have an overview of the power condition of the amplifier board. This board is in 3.6’’ x 2.7’’ compact size, which can be easily integrated into any audio projects without occupation of too much space.
