Dual Range DC Power Supplies
Models 1737 & 1747
B&K Precision’s models 1737 and 1747 are
general purpose dual range DC power sources.
These power supplies can output higher voltage
at a lower current range or more current at a
lower voltage range. Two 4-digit LED displays
continuously monitor the output voltage and
current. The power supplies can be operated
locally from the front panel or remotely through
the RS-232 interface.

The 1737 and 1747 both exhibit excellent
regulation and low ripple characteristics. Their
mechanical configuration conserves bench space
and allows for easy portability.
These power supplies are well-suited for a wide
variety of electrical and electronics applications in
service shops, engineering labs, production,
school laboratories, and home use.

Two Power Supplies in One
The 1737 and 1747's unique dual range
feature offers the best of both worlds by
supplying two different ranges with either
higher voltage or more current depending
on your application, avoiding the higher
cost of buying more power than necessary.
