Atec Sorensen-SG Series - Manual (Page 2)

Advanced Power Simulation
SGI model provides
constant power mode allowing
independent setting of the max
voltage, current and power
The SG series represents the next generation of high power
programmable DC power supplies. Designed for exceptional load
transient response, low noise and the highest power density in the
industry. The industry leading 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 SG series 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 current. Available in two control versions, the SGA has basic
analog controls, while the SGI provides intelligent control features
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 idea 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.
SGA: Outstanding Value - Analog Control
(Sorensen General purpose Analog) The SGA, with its industry
leading price performance, is available for customers requiring
simple front panel analog controls or external control. With the
same high performance power electronics as the SGI, the SGA
provides essential features like 10- turn potentiometers for setting
voltage and current, 3 ½ digit LED readout plus front panel
over-voltage protection (OVP) preview/adjustment and reset.
