GPS-2303	DC Power Supply - 0-30Vx2,0-3AX2	$370.00	$333.00

The regulated DC power supply series is designed to be used in applications such as powering operational amplifier, push-pull stages, logic circuit and definition systems where plus and minus voltages are required to track with an insignificant error. To represent an operation convenience, GPS-2303 has two independent power supplies housed in a single package.

GPS-2303 consist of two identical, independent, adjustable DC power supplies. A front panel switch selects one of three operation modes of independent, series and parallel. In the independent mode, the output voltage and current of each supply are controlled separately, and each supply is isolated up to 300V from output to chassis or output to output. In the tracking mode, both outputs are automatically connected in series or parallel, and the controls of the left supply adjust the magnitudes of both the positive and negative output voltages. Because the outputs are connected in a tracking configuration, any internal disturbance in the master supply (such as drift or ripple) will cause an equal percentage change in the outputs of both the supplies.
