1. Outline
1.1 Overview
The DP series offers a compact, lightweight, and highly-efficient power system, ranging from
single-phase 1.5 kVA to three-phase 36 kVA at a maximum. It also provides various interfaces such
as the external control input/output, communication interface, and remote controller (some of them
are optional) to address a wide variety of usage. You can configure several products of same
single-phase model to participate in a single-phase three-wire system or three-phase four-wire
system by using a System Cable (optional).
The AC output of DP series ranges from 0 to 310 V for voltage (phase voltage) and 1 to 550 Hz for
frequency, and the DC voltage output ranges from −440 V to +440 V. The maximum output current
(phase current) is 120 Arms continuous (single-phase 12 kVA, 100 V range), and if you use a
capacitor input type rectified load, you can output a peak value of 480 Apk at a maximum
(single-phase 12 kVA, 100 V range, crest factor of 4).
1.2 Series Line-up and Polyphase System Configuration
In the DP series, multiple models (single-phase model, polyphase model) are available with various
combinations of output capacity and output phase mode. The lineups of single-phase model and
polyphase model are listed in Table 1-1.
The D
(single-phase two-wire, single-phase three-wire, or three-phase four-wire) on a cabinet. When you
set the "phase mode setting switch" of the Multi-phase model and then turn on the power, the model
operates as single-phase model or polyphase model as shown in Table 1-2. The operation

1.3 Features
Various interfaces to address a variety of usage
In addition to RS232, USB, and GPIB (optional) to use for the remote controlling from a computer
or sequencer, you can use a contact/TTL signal to turn the output on/off or switch the memory
without using a computer. The product also offers the status output for showing the device status
and the output which is synchronized with Sequence or Simulation (optional) step. With these
functions you can achieve various types of systemization and automatization. The AGC function
(optional) and Autocal function for calibrating the output voltage drop are also provided.
Variable current limiter
This function can limit the effective value and the positive/negative peak value of the output current
where the limiting value is variable. You can set the limiter so that the output is turned off when the
limited condition continues for a certain time.
Globally adjustable power inlet without restricted by the power supply environment
The DP series supports a wide range of power input from 100 V to 230 V. However, with the model
of which the output capacity is 6 kVA or more, the output power capacity will be limited when the
power input is 170 V or less.
Feature-rich measurement function
On the panel the product displays the effective value, peak value, average DC value, current
peak-hold value, and active/apparent power of the output voltage/current. Furthermore, the power
factor, crest factor, reactive power, and harmonic current are also measured and displayed by
additional options.

About outlet
If you purchase a single-phase model, you need to specify the outlet type to either NEMA 5-15
(Japan/North America type) or CEE 7 (Europe type). The model name of this product is
distinguished by this outlet type (Figure 1–1). The output terminals, the maximum voltage, the
m
aximum current, and available output range are listed for each type in Table 2-7.
Each outlet can pro
vide up to 15 A of current. If a current exceeding 15 A flows, the circuit breaker
may operate to cut the output. When the circuit breaker operates, the button is pushed out forward.
Pushing in this button resets the breaker, and power can be provided from the outlet.
The outlet is dedicated to AC output. It can be used in the AC or ACDC mode. In the settings below,
the outlet is separated from the output by the internal relay of this product. However, only the Hi
terminal is separated.

2.5.4 Polyphase System
System Cable (1P3W)
System Cable (3P4W)
Single-phase three-wire system Three-phase four-wire system
Optional System Cable should be connected to the SYSTEM I/O connector of this product. The
cabinet which the L1 connector of the System Cable is connected to becomes L1 phase, and the
output terminals Hi and Lo correspond to the L1 and N terminals, respectively. This is same for L2
and L3 phases. This product recognizes the polyphase system by checking the state of the system
cable connection at power-on, so connect the System Cable before turning on the power.
-------- Notes----------------------------------------------------------------------------------------------------------------
The polyphase system can be configured only when the same single-phase models are
connected with System Cables.
The models with different model names cannot be connected.
Connection with polyphase model or Multi-phase model is not allowed.
You cannot use a Multi-phase model to configure a polyphase system, even when it is used as
a single-phase output.
You cannot connect single-phase models in parallel to boost up a single-phase output.
Turn on all power supplies within 20 seconds.
The L2 and L3 cabinets in a polyphase system are restricted in their operation as follows:
Cannot use the communication interface (USB, RS232, GPIB).
Cannot use the external control.
Cannot use a USB memory.
Cannot connect and use the remote controller.
Starts according to the contents of the Basic Setting Memory No.1 of the L1 cabinet.
Does not accept the control panel key operations except for special cases.
Can only display the output measured value of their own cabinet in the measurement display.
The display format of the measured value (
3.4.10) follows that of the LI cabinet.

terminal of each cabinet. The neutral line can be connected to the Lo terminal with two methods
described below. The neutral line can be grounded. If the load has a ground terminal, connect it
to the ground terminal of each output terminal. Be sure to tighten the screws firmly.
(a) When connecting the load with the neutral line (single-phase three-wire or three-phase
four-wire connection)
Connect the neutral point of load with the Lo terminal of each cabinet using cables with
same length and diameter as the voltage line. Alternatively, connect between the Lo
terminals of each cabinet by a cable which is as short as possible and has a diameter equal
to or more than that of the voltage line, and then connect one of the Lo terminals with the
neutral point of load by a cable with same length and diameter as the voltage line.
(b) When not connecting the load with the neutral line (three-phase three-wire connection),
Connect between the Lo terminals of each cabinet by a cable which is as short and thick as
possible (with a diameter equal to or more than that of the voltage line).
CAUTION
The terminal which can be grounded is the Lo terminal of each cabinet. Do not ground the Hi
terminal (L1, L2, and L3 voltage lines).

4.1.3 Using Voltage Setting Range Limit
For the continuous output function, when the signal source is INT, SYNC, or ADD, the range of the
output voltage setting value to the internal signal source can be limited. Even if trying to set a
voltage that exceeds the limit, the setting value is restricted to the limiting value. This can prevent
mis-setting when you do not want to set values outside the range.
As for the voltage setting range limiting values, each value is kept independently for the following
settings for 100 V and 200 V ranges respectively: SIN/CLP waveform in AC mode, ARB waveform
in AC mode, ACDC mode, and DC mode.
In case of polyphase output, the setting of the voltage setting range limit is common to all phases,
and kept as the effective value of the phase voltage in this product. When the line voltage setting
(effective value setting) is selected in balanced mode, it is converted into the effective value setting
of the phase voltage according to the following formula and kept in this product.

The limiting value should be set using the effective value or the positive and negative peak value.
The effective value can be used only when in the AC mode and the waveform is a sine wave or a

4.1.5 About Wattage Limiter

Note: Power input 100 V system is for power input voltage 170 V or less.
-------- Notes----------------------------------------------------------------------------------------------------------------
If the wattage limiter operates, suppress the output wattage within the rated output power by
lowering the output voltage setting value.
Active power (unit: W) is restricted by the wattage limiter, however, reactive power (unit: var)
is not restricted. Therefore, the apparent power (unit: VA) may exceed the rated power
depending on the power factor of the load. Set the output voltage so that the apparent power
does not exceed the rated power, regardless of the operation of the wattage limiter.
The value of the wattage limiter cannot be changed. To limit the output power to a value that is
lower than the rating, decrease the number of power units that are energized through the power
unit energization setting, or use the peak current limiter or the RMS current limiter.
When the power input voltage is 170 V or less, the maximum output active power of a model
with the rated power of 6 kVA or higher is limited to 4.725 kW of maximum output active
power by the wattage limiter. However, for a single-phase three-wire model and a three-phase
model, the maximum output active power per phase is limited to 4.725 kW/2 and 4.725 kW/3.

4.2 Using Sequence Function
4.2.1 Basics
By using Sequence function (optional), an output setting can be changed step-by-step according to
the program (sequence) created beforehand. This section describes the basics for using the Sequence
function.
AC/DC Mode and Signal Source
Sequence function keeps the selection of the AC/DC mode and a signal source, independently from
continuous output function/Simulation function. AC/DC mode can be selected from AC/ACDC/DC.
A signal source is fixed as INT.
DP Series

Page 94
4. Advanced Operation
Keep a sequence setting
The sequence setting is kept per AC/DC mode. Every time AC/DC mode is changed, the sequence
setting that is already kept is loaded. The sequence setting is cleared when the power is turned off.
To save the setting, you need to save it in internal memory or USB memory (see 4.9).
St
ep
One sequence consists of a series of two or more steps. To use Sequence function, first set each step.
Step-control Parameters and intra-Step Parameters
There are the following two major types of parameters in Sequence function:
Step-control parameter
Parameter to control the flow between two or more steps. This defines duration of each step
and the next step to transition. Settings of step synchronous code and trigger output are
included in step-control parameter for convenience.
Intra-Step parameter
Parameter to define output state in each step. This defines basic parameters such as a
waveform, frequency, and how they are changed in the step.

Step Behavior (Const, Keep, Sweep)
For the intra-Step parameter other than waveforms and phases, the following three patterns can be
set as the method to change values in the step.
Constant (Const)
Fixed to the value set in the step.
Keep (Keep)
Keeping the value immediately before transitioning to the step. That is, the value is changed
depending on the status of the previous step. Although the parameter value can be set even if
the operation type setting is Keep, the parameter setting value is ignored when sequence is
executed.
Sweep
It changes linearly from the value immediately before transitioning to the value set in the step,
taking the Step Times. In other words, it reaches the setting value after the Step Time passes in
the step. The starting value is changed depending on the status of the previous step.

Keeps as many intra-Step parameter setting values as the number of phases in each step based
on the output phase mode.
Cannot be set using line voltage in the single-phase three-wire output and three-phase output.
The rate of crest factor/clip ratio cannot be changed though a clipped sine wave can be selected
as an output waveform in Sequence function. Set these parameters beforehand using
continuous output function.
Sequence function displays the measured value in Sequence function, which is equivalent to
that of the continuous output function. However, harmonic current measurement (see 4.4)

4.2.2 Parameters of Sequence Function
Table 4-2 shows the parameters of Sequence function. The common parameters are common to one
sequence. In Sequence function, signal source is fixed to INT. In each step, set the step-control
parameter and the intra-Step parameter. As for intra-Step parameter, the item and range that can be
set differ depending on the output range (100 V/200 V range) and output mode
(AC-INT/ACDC-INT/DC-INT) as in the case of continuous output function. This section describes
intra-Step parameters and step-control parameters separately.
Table 4-2 Parameters of Sequence Function
Common
parameter

AC/DC mode
Frequency (Freq), waveform (Wave), phase angle (Phase), AC phase voltage (ACV), DC
voltage (DCV)
The setting for the output of each step. In polyphase model/polyphase system, AC phase voltage and
phase angle can be set for each phase. In the phase angle, set the phase difference with the L1 phase.
Phase angle can also be set per step. The phase angle of L1 phase cannot be set, and is fixed as 0
deg.
Step Time (Step Time)
Set the output time of that step. Unit can be selected from [s] or [ms].
Jump-to step (Jump To)
When selected, the destination step of the jump at the end of the step can be specified. By specifying
the Jump count ([Jump Cnt]), you can set up a loop to repeat the same step. After jumping for the
times specified for one sequence, the action at the end of step follows the step termination setting.
If Jump-to is set to off, the action at the end of step follows the step termination setting.

Jump count (Jump Cnt)
Number of times of jumps to jump to the step specified in Jump-to. This can be set when Jump-to
([Jump To]) is selected. When the Jump count is set to 0, infinite times of jumps occur.
-------- Notes----------------------------------------------------------------------------------------------------------------
The number of times that a particular step is repeated is Jump count +1.
---------------------------------------------------------------------------------------------------------------------------------
Branch step (Branch1, Branch2)
When the step is under execution or in the hold state, the step to transition when the branching
instruction through panel operation or external control is detected can be specified. There are two
systems of branch instructions (Branch1 and Branch2), and an instruction can be set for each.
-------- Notes----------------------------------------------------------------------------------------------------------------
Transition using branch is executed immediately after a branching instruction is detected. Step
Time, Stop Phase, and step termination setting are ignored.
---------------------------------------------------------------------------------------------------------------------------------
Step termination (Step Term)
Specifies the action when the step completes. When [Continue] is selected, transitions to the step of
the next number. When [End] is selected, the sequence is terminated and the execution transitions to
step No. 0 and enter into the stand-by state. When [Hold] is selected, the output at the end of the step
is suspended, and the execution transitions to the step of the next number when Resume instruction
is detected.
-------- Notes----------------------------------------------------------------------------------------------------------------
When [Step Term] is set to [Hold], the execution enters into hold state before jump. Jumps
when Resume instruction is detected.
When [Step Term] is set to [Hold], after the jumps repeated for the specified Jump count, the
execution transitions to the step of the next number when Resume instruction is detected in
hold state.
While in the hold state due to the step termination in a step where step termination phase is
enabled, the execution transitions to Jump-to step or the step of next number when Resume
instruction is detected, after the hold state is kept until Stop Phase.
---------------------------------------------------------------------------------------------------------------------------------
Step sync code output (Code)
State output to CONTROL I/O connector. Code to output while the execution of the step, which is
specified by 2-bit H/L.
Start Phase (StartPhs)
Determines the phase of AC waveform of L1 phase when the step starts. The phase when a step
starts in L2 and L3 phase of polyphase model/polyphase system is the addition of the setting value
of intra-Step parameter Phase and the setting value of the step Start Phase.
DP Series
79
Page 98
4. Advanced Operation
-------- Notes----------------------------------------------------------------------------------------------------------------
Step Start Phase setting can be disabled. In that case, the phase when the phase starts becomes
the phase when the previous step ended.
In DC mode, the step Start Phase cannot be set.
---------------------------------------------------------------------------------------------------------------------------------
Stop Phase (Stop Phs)
Determines the phase of AC waveform when the step ends. The phase when a step ends in L2 and L3
phase of polyphase model/polyphase system is the addition of the setting value of intra-Step
parameter Phase and the setting value of the step Stop Phase. When the stop phase setting is active,
the execution waits for the Step Time that was set pass, and keeps the output setting until it reaches
the Stop Phase that was set, and then transitions to the next step. As the result, the actual step time is
longer by one cycle at a maximum than the set Step Time. Figure 4–3 shows an example where both
the S
top Phase of the previous step and the Start Phase of the next step are set to 0°.

When the Step Behavior is set to [Sweep], output is constant while waiting for the step Stop
Phase after the Step Time passes.
Step Stop Phase setting can be disabled. In this case, when the set Step Time has passed, the
execution transitions to the next step without waiting for step Stop Phase.
In DC mode, the step Stop Phase cannot be set.
---------------------------------------------------------------------------------------------------------------------------------
Trigger output (Trig Out)
State output to CONTROL I/O connector. This specifies whether the trigger output presents when
the step starts. Polarity and pulse width of the trigger output complies to the trigger output setting
(see 4.2.5).
