Description
Product Resume
This power supply is ideally suited for use with amplifier projects. The regulated 5 VDC, 60A 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.
