B+K Precision
®
Series1740 are 0 to 60V, 0 to 10A DC Power
Supplies. 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, these features include an output On/Off
button and a output-shorting button. The output-shorting
button allows the user to short the output terminals to set the
current limit.
■ Largest selection of voltage and
current ratings ever offered
■ Connect two supplies in parallel
to double the current output
■ Connect two supplies in series
to double the voltage output
