from 4 to 30 kW
• Fast Load Transient Response: Protection from
undesired voltage excursions

• Sequencing: Free system controller & speed up test
• Low audible noise: Temperature controlled variable
speed fans
The Sorensen SG Series (hereafter SG Series)
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. With a full 15 kW
available down to 20VDC output in a 3U package
the SG leads the industry in power density. 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 SG series is a 5 kW power
module. Depending on the output voltage, one
to six modules can be congured 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 ideal for repetitive
testing. An impressive vacuum uorescent
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 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.
