Description

This power supply is ideally suited for use with amplifier projects. The regulated 12 VDC, 29A design is capable of delivering 350watts of output. Overload, over voltage, and over temperature protection is built-in, shutting down the power supply to prevent damage and then restoring power upon recovery.
