SORENSEN SGI60-500 DC Power Supply  The Sorensen SGI60-500 represents the next generation of high power programmable DC power supplies. The SG Series 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. At the heart of the SGI60-500 is a 5 kW power module. Depending on the output voltage, one to six modules can be configured in a single chassis to deliver 5 kW to 30 kW 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.SGI: Advanced Intelligent Control (Sorensen General purpose Intelligent): 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. Looping of sequences makes the SGI ideal for repetitive testing. An impressive vacuum fluorescent graphical display in eight languages, context sensitive “soft” keys and front panel keyboard simplify programming of the SGI. Specifications for the SORENSEN SGI60-500 DC Power Supply  Include: See Datasheet for full specifications      Product Overview  SORENSEN SGI60-83 POWER SUPPLY (call for availability) The Sorensen SGI60-83 is a general purpose power supply designed specifically for laboratory test and systems applications requiring variable DC sources with good ripple and regulation characteristics. Features and Specifications of the Sorensen SGI60-83 Power Supply include:
