Load effect: also known as “load
regulation”. Load effect is the change
in the steady-state value of the
stabilized output voltage or current
resulting from a full-load change
in the load current of a constant-
voltage supply or the load voltage
of a constant-current supply, with
all other influence quantities
maintained constant.
Load effect transient recovery time: the
time interval between a specified
step change in the load current of a
constant-voltage supply (usually a
full-load or 5-amp change, whichever
is smaller) or in the load voltage of
a constant-current supply and the
instant when the stabilized output
quantity returns to and stays within
a specified transient recovery band.

Master-slave operation: a method of
interconnecting two or more sup-
plies or electronic loads such that
one of them (the master) serves
to control the others (the slaves).
The outputs of the slave supplies or
inputs of the slave electronic loads
always remain equal to or propor-
tional to the output of the master.
The outputs of the master supply
and of one or more slaves may be
connected in series, in parallel, or
with just their negative or positive
output terminals in common. (See
also “complementary tracking”).
The inputs of the master electronic
load and one or more slaves may be
connected in parallel only.
Minimum transition time: the shortest
possible time in which an electronic
load input can change from one
level to another. This is determined
by the small signal bandwidth of
the load.
Modulation: analog programming of
the output voltage and/or current.
The output programming response
time determines the maximum slew
rate at which the power supplies
output can be programmed.
Nominal value: the value that exists
“in name only”; not the actual value.
For example, in the case of a power
supply with a calibrated output
control, the nominal value is the
value indicated by the control
setting. For a supply with a fixed
output, the nominal output is the
output indicated on the nameplate.
The nominal value of a 120-volt
±10% line voltage is 120 volts.
“One-box”: a power supply that can
be controlled by direct connection
to a computer (with no additional
programmers) and that can provide
measured data to a computer
without external voltmeters or
ammeters.
