SORENSEN SGI200-100 DC Power Supply  The Sorensen SGI200-100 represents the next generation of high power programmable DC power supplies. It is designed for exceptional load transient response, low noise and the highest power density in the industry.  The power density is enhanced by a stylish front air intake allowing supplies to be stacked without any required clearance between units.  The SGI combines onboard intelligent controls with the outstanding power electronics common to all SG family supplies. These controls enable sophisticated sequencing, constant power mode and save/recall of instrument settings.At the heart of the Sorensen SGI200-100 is a 5 kW power module. Four modules are configured in a single chassis to deliver 20kW of power.  Combinations of these chassis can then be easily paralleled to achieve power levels up to 150 kW. Paralleled units operate like one single supply providing total system cur.  Looping of sequences makes the SGI200-100 ideal for repetitive testing. An impressive vacuum fluorescent graphical display in eight languages, context sensitive “soft” keys and front panel keyboard simplify programming. Specifications of the SORENSEN SGI200-100 DC Power Supply includes:  See Datasheet for Full Specifications
