B+K Precision models 1744A and 1745A are a 0 to 35V, 0
to 10A DC Power Supply. These power supplies have all
of the great features you would expect B+K Precision
power supplies to have and some new features not
normally seen on power supplies in this price range,
including an output-shorting button. The output-shorting
button allows the user to short the output terminals to set
the current limit.
