GPS -3303 is a 3-channel linear DC power supply with 195W output. Overload and polarity reversal protection and output control switch can protect GPS and load from accidental damage. Each channel has a high regulation rate of 0.01% and ripple and noise of less than 1mVrms. The intelligent fan can automatically adjust the speed according to the load condition to ensure a quiet operating environment. The GPS series is cheap, lightweight, and has a low rate of change and multiple outputs, making it an ideal power s This model is discontinued and replaced by the new model GPS3323A.
