B+K Precision models 1744A and 1745A are 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. 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

■ Reliable, Durable

■ Operate continuously at full load without

overheating

■ Fully overload protected

■ Coarse and fine voltage controls

■ Excellent regulation

■ Ve ry low ripple

■ Constant voltage or constant current

operation

■Continuously monitor voltage and cur-

rent output on two meters
