Because controlled electrical energy is useful in
myriad testing situations, the power supply is an
exceedingly popular piece of electronic test
equipment. Although anything which supplies power
for example, a combustion engine can be
broadly defined as a power supply, well limit
our discussion to types of DC power supply units
that are commonly used for development,
maintenance, measurement, and testing.

1st DC Power Supply Type Constant
Voltage/Current
The constant voltage/current power supply, which
as the name implies provides constant voltage as
well as constant current, is perhaps the most
popular variety of power supply. When operating
in constant current mode, these power supplies
maintain their set current even as the resistance
of the load changes. Constant voltage/constant
current power supplies frequency has features
including remote sensing, master/slave
connections, and analog programming (remote
programming terminals).

2nd DC Power Supply Type Multiple Outputs
Multiple output power supplies typically have two
or three outputs. If you find that you often use
multiple voltages while testing, a multiple
output DC power supply type is the cost-effective
choice. Many users opt for a triple-output power
supply which provides one output for digital
logic and two outputs for bipolar analog
circuitry. Some common features include timed
operation, settable voltage limitations, storage
registers for up to fifty instrument states, and
the ability to connect two channels in parallel
or series for higher current or voltage.

3rd DC Power Supply Type Programmable
Because they are generally used in conjunction
with a computer-operated system for production
and testing, programmable power supplies are
often referred to as system power supplies.
System power supplies have used a number of
computer interfaces in the past, two of which -
IEEE-488, or GPIB (general purpose interface
bus), and RS-232 serial communications have
been widely used. Ethernet and USB interfaces
have also been quite common.

In addition, these DC power supply types have
command languages for sending instructions to the
instrument through the digital interface. These
languages include proprietary, SCPI (standard
commands for programmable instruments), and
SCPI-like. The ability to control a programmable
power supply via your computer, instead of
pushing keys on the instruments front panel,
makes this type of power supply especially useful
when working on complex setups.
