Mean Well NES-35-24 24V 35W AC/DC Switching Power Supply




This low power stereo audio amplifier board produces 15W per channel into an 8Ohm load based on Class D topology and MAX9736A chip, featuring low power consumption and high efficiency as 87.2%. Compact size, easy installation and low power output makes this audio amplifier board suitable for home audio, DIY audio, toy audio and demanding industrial applications. It operates from 8V to 28V and provides high PSRR, eliminating the need for a regulated power supply.

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 is 89.4dB and THD+N performs well as 0.0495% @ 8Ohm, 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. Thanks to the pre-mounted industrial terminal interfaces, all you need to do is to plug in cables for connection, without any demand of soldering, which is swift and convenient. Power indicator is provided on board for customers to have an overview of the real-time condition of the amplifier board.
