Sequence Operation
❏
or
❍
/
●
Setting the times for the sequence pattern of voltage, frequency or
impedance allows that sequence pattern to be run, stopped or repeated
as desired.
7
Output Impedance Setting
❏
or
❍
/
●
The output impedance of the PCR-L series is nearly 0
Ω
. However,
actual commercial power supplies have an impedance (resistance)
on the order of several m
Ω
. The members of the PCR-L series there-
fore allow output impedance to be varied to closely match actual
power supply environments.

Power Factor, VA and
Peak Hold Current Measurements
❏
or
❍
/
●
In addition to these power supplies being equipped with a diverse
range of measuring functions, those functions can be further expanded
by connecting various options. Expanded functions consist of "power
factor measurement", "VA measurement" and "peak hold current
measurement". Measurement of peak hold current involves measur-
ing the peak current until the power supply receives a peak clear
signal or command. This is useful for measuring rush current and so
on.
9
AC+DC Mode
❏
or
❍
/
●
This function allows output of voltage waveforms in which AC volt-
age is superimposed on DC voltage. This mode allows these power
supplies to be used not only for various electronic devices, but for
chemical experiments and production equipment as well.
10
Memory Function Expansion
❏
or
❍
/
●
These power supplies allows storage of 9 sets of voltage and fre-
quency settings as a standard feature (at memory addresses 1-9). These
settings can then be read out and output as necessary. The adding of
a memory expansion option allows up 99 sets of voltage and fre-
quency settings to be stored in memory. In the AC+DC mode, AC
memory values and DC memory values are output simultaneously
thereby allowing memory operation in the AC+DC mode.
11
Regulation Adjustment
❏
This function is used for the same purpose as the "sensing function".
The sensing function measures the voltage at a specific sensing point
and then holds the voltage of that sensing point constant. In contrast,
the regulation adjustment function calculates the voltage drop caused
by output current and then raises the output voltage by the amount of
that drop. This function is used for stabilizing the voltage at the load
end when the power supply and load are located at a considerable
distance from each other.
Note: When using the regulation adjustment function, the voltage stabilization accuracy,
distortion factor and response speed will decrease below the level of performance
of the power supply.

Output Phase Setting
❏
or
❍
/
●
The timing by which the output is
switched on and off can be arbi-
trarily set with the phase of the volt-
age waveform. Combining this
phase setting function with the cur-
rent peak hold function greatly fa-
cilitates measurement of rush cur-
rent.
Output ON/OFF Phase Setting
Output on phase: 90 deg.
Output off phase: 0 deg

Harmonics Current Analysis Function
❏
or
❍
/
●
This function performs analysis of harmonics current for output cur-
rent from the power supply. Although this measurement was con-
ventionally measured using an FFT analyzer, the use of these power
supplies eliminates the need for this device. In addition, the use of a
standardized line impedance network as shown in the diagram below
also allows simulation of commercial power supplies.
