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. The Sorensen SGI40x375 Precision Programmable DC Power Supply 40 Volts, 375 Amps is a general-purpose power supply designed specifically for laboratory test and systems applications requiring variable DC sources with good ripple and regulation characteristics. These power supplies are constant current/constant voltage supplies with an automatic crossover features. A variety of user interfaces are available, ranging from manual front-panel control and standard non-isolated remote analog control, to optional GPIB or isolated remote analog control.
