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

Very low ripple

Constant voltage or constant current

operation

Continuously monitor voltage and cur-

rent output on two meters
