Description
Product Resume
This power supply is ideally suited for use with amplifier projects. The regulated 24 VDC, 8.8A design is capable of delivering 200watts of output. Overload, over voltage, and short circuit protection is built-in, shutting down the power supply to prevent damage and then restoring power upon recovery.
