Introduction System Overview
The IMACS-200 offers a range of power input options, which are selected to be the most
commonly used input voltages in use by our various customers. They are: -48VDC, 125VDC,
120VAC and 220VAC. The power supply modules are factory installed, and will come with
the proper connectors configured for the IMACS-200 powering options you have selected.
The power inputs are to the right and left rear of the IMACS-200, and labeled accordingly. In
Figure 1-2, the supply inputs are seen on the sides of the rear panel.
