Chapter 1
General
Provides an overview of the Single-phase, Three-wire Output Driver
and describes its features. Also denotes parts names and descriptions.
1.1
Outline
This device (2P03-PCR-LA) is an option for operating the PCR-LA
Series AC power supplies in single-phase, three-wire output.
Use of the Single-phase, Three-wire Output Driver allows the outputs
of two PCR-LA AC power supplies to be connected in series for use
as single-phase, three-wire system power supplies.
1.2
Features
Use of this device allows the PCR-LA AC power supplies to provide
the following enhanced functions, in addition to the PCR-LA power
supply’s standard functions.
Single-phase Three-wire Output
Use of this device allows two PCR-LA AC power supplies to generate
single-phase, three-wire outputs, in which the U-phase unit of the two
power supplies acts as a master and their V-phase unit act as a slave.
Setting of Either Line Voltage or Phase Voltage
The line voltage can also be set in addition to the phase voltage.
Line Voltage Measurement
Connecting the SENSING terminal board at the terminal box of the
PCR-LA AC power supply to a line voltage measurement point
allows measurement of the line voltage.
Measurements of the Total Power, Total Apparent
Power, and Total Power Factor of Single-phase,
Three-wire Output
Use of this output driver allows for the display of total power and
total apparent power obtained through measurements using the two
PCR-LA AC power supplies. The total power factor of the two phases
can also be calculated from these total values.
2P03-PCR-LA

Operation Method
Describes the operations and functions of the 2P03-PCR-LA Singlephase, Three-wire Output Driver.
This Operation Manual describes the procedures for use of the functions available in single-phase, three-wire operation that differ from
those available when a PCR-LA power supply is used in single-phase
operation. For information not provided in this manual, see the PCRLA AC Power Supply Operation Manual. Moreover, before reading
the 2P03-PCR-LA Operation Manual, always read through the PCRLA AC Power Supply Operation Manual.
NOTE
3.1
• Unless otherwise specified, the operation method described in
this chapter applies to the U-phase power supply.
Operation Check
Before conducting an operation check of single-phase, three-wire
operation, confirm the connections of each PCR-LA power supply by
referring to Chapter 2 “Precautions and Preparation for Use”.
CAUTION • To protect a load, carry out an operation check without connecting a load. If a load has been connected
to the PCR-LA power supplies, disconnect it.
Operation Check Procedure
Principally, check the following items in the same way as in “2.7 Operation Check” in the PCR-LA AC Power Supply Operation Manual.
• POWER switch ON
• Voltage setting
• OUTPUT ON/OFF
• Voltage-range switching
For operations specific to single-phase, three-wire operation, see “3.2 Basic
Operation Required for Single-phase, Three-wire Operation” onward.
NOTE
• Even if one power supply is not connected or an error occurs
in either of the two power supplies, neither of the PCR-LA
power supplies operate.
2P03-PCR-LA
Operation Method 3-1
3.2
Basic Operation Required for
Single-phase, Three-wire Operation
The basic operation for single-phase, three-wire operation is as
described below.
POWER-switch operation
• When turning the POWER switches ON, turn the POWER switch
of the V-phase power supply ON first, followed by the U-phase
power supply POWER switch. Alternatively, turn the POWER
switches of both two power supplies ON simultaneously.
• When turning ON (or OFF) both PCR-LA power supply POWER
switches, complete both turn-ONs within three seconds.
NOTE
• If the turn-ON procedure for the POWER switches is
improper, the AC power supplies may not start up. In such a
case, turn OFF all POWER switches and then turn them ON
again by the correct procedure.
Operation and Indications of the Control Panel
• During single-phase, three-wire operation, the U-phase power supply acts as the master to control the V-power supply. Thus, to
change a setting, use the U-phase power supply control panel. Values set through the U-phase power supply control panel will be set
to the V-phase power supply in the same way.
• In phase voltage setting, the voltage concerned can be set from the
V-phase power supply control panel. This setting changes only the
voltage of the V-phase power supply.
DESCRIPTION
• Difference in Display between Single-phase and
Single-phase, Three-wire Operations
When this device is installed in the PCR-LA power supplies to
perform single-phase, three-wire operation, part of the control
panel display differs from that provided for single-phase operation.
(1) Indications common to each phase
• The
symbol and the letter “U” or “V” at the left of
the voltage display area indicate that a PCR-LA AC
power supply has been set to the relevant phase and that
the voltage reading shows the phase voltage.
• The letters “U-V” at the left of the voltage display area indi-
3-2 Operation Method
2P03-PCR-LA
cate that the voltage reading shows the line voltage of the
power supplies concerned (U-phase power supply only.)
(2) Display on the V-phase power supply control panel
• This control panels display the phase (V) indication,
voltage and current values, and LOAD level meter indication only.
(3) U-phase power supply control panel display
• During display of the power, the
symbol and the letters “U” and “V” may all appear at the left of the current
display area. This indicates the total power of the singlephase, three-wire.
• During a self-test, the
symbol and the letter “U” or
“V” may appear at the left of the voltage display area.
This indicates the self-test result for the AC power supply of the displayed phase.
2P03-PCR-LA
Operation Method 3-3
3.3
Switching between Phase Voltage and
Line Voltage Displays
The phase voltage display and line voltage display modes for display
are provided for single-phase, three-wire operation. The display mode
will be backed up and, when the POWER switch is turned ON, the
display mode used immediately before the POWER switch was
turned OFF will be selected.
1. Press the ESC key to select the Home Position.
2. Press the PHASE (SHIFT, 2) key.
Each time the PHASE key is pressed, the display mode is
switched between phase voltage display and line voltage display.
Phase Voltage Display Mode
• The
symbol and letter “U” or “V” at the left of the voltage display area indicate that the phase voltage display mode is selected.
Line Voltage Display Mode
• The letters “U-V” at the left of the voltage display area indicate that
the line voltage display mode is selected.
• Setting the voltage in the line voltage display mode allows line
voltage setting.
• The line voltage display mode disables the measurement of output
power.
• In the line voltage display mode, the V-phase voltage cannot be set
separately.
3.4
Output Voltage Setting
• Setting the voltage value to the U-phase power supply causes the
voltage of V-phase to be the same.
• Setting a voltage value to the V-phase power supply causes only the
V-phase voltage to change. However, changing the U-phase voltage
afterward causes the V-phase voltage to change to the same value as
the U-phase voltage.
• Setting of the V-phase voltage requires selection of the phase voltage display mode.
To set the voltage using the numeric keys in the OUTPUT ON condition, select the SET mode on the U-phase power supply.
3-4 Operation Method
2P03-PCR-LA
• Voltage setting in the phase voltage display mode sets the phase
voltage; set the voltage to 1/2 of the voltage required between lines.
• Voltage setting in the line voltage display mode sets the line voltage; set the voltage required between lines and leave as is.
• For the voltage setting methods and others, see the PCR-LA AC
Power Supply Operation Manual.
3.5
Limit Value Setting
• Voltage and frequency limit values should be set through the Uphase power supply control panel. The values set on the U-phase
power supply apply to V-phase.
• A voltage limit value is a limit on the phase voltage; a line voltage
limit operates at a value twice the phase voltage limit.
• The current limit value should be set on a phase basis.
3.6
Setting the Current or Power Display
Mode
• Each time the I MODE (SHIFT, I) key is pressed, the current and
power display modes change as follows:
Display of the U-phase power supply
RMS
PEAK
W (U-phase power)
W (total power of the
single-phase, three-wire)
Display of the V-phase power supply
RMS
PEAK
W (V-phase power)
W (V-phase power)
If the output power exceeds 10 kW, “E3” appears on the control
panel.
Example: For output power of 12 000 W, the control panel displays
the following.
W

Operation Method 3-5
3.7
Memory Function
• The memory function is available only in the phase voltage display
mode.
• The U-phase power supply allows the voltage and frequency to be
stored in the memory.
• The V-phase power supply allows only the voltage to be stored in
the memory.
• The voltage read from the U-phase power supply memory is also
set to V-phase.
3.8
Key-lock Function
• The key-lock function operates in all phases separately.
3.9
Self-test Function
For single-phase, three-wire operation, the self-test is also conducted
from the U-phase power supply. It will be performed on both two AC
power supplies.
• The self-test operating procedure is as described in the “Alarm-type
checking procedure (SELF TEST)” in “4.6.1 Steps to be Taken in
the Event of an Alarm” in the PCR-LA AC Power Supply Operation Manual.
• If an alarm occurs, the U-phase power supply always generates an
intermittent buzzer tone and displays an “ALARM” indication.
• Some types of alarms also cause an intermittent buzzer tone to be
generated from and an “ALARM” indication to be displayed on the
V-phase power supply in which an alarm has occurred, in addition
to the U-phase power supply.
• Turning JOG causes the numbers in “Ad.” and “No.” to change, in
addition to the letter “U” or “V” at the left of the voltage display
area. Each letter indicates that the relevant phase power supply is
under self-testing.
• When the three power supplies are operated individually in parallel,
the numbers in “Ad.” for these power supplies are as shown in
Table 3-1.
• The numbers in “Ad.” shown in Table 3-1 are displayed on all of the
3-6 Operation Method

The words “Master” and “Slave” in Table 3-1 represent the relationship
between the master and slave units in parallel connection.
When this device is combined with the Parallel Operation Driver to
perform parallel operation in a single-phase, three-wire system, the
number of power supplies to be operated in parallel is up to three for
each phase.
3.10 Functions Restricted during
Single-phase, Three-wire Operation
During single-phase, three-wire operation, the PCR-LA power supply
functions will be partially restricted. The following functions are not
available when the Single-phase, Three-wire Output Driver is
installed in PCR-LA AC power supplies.
• DC mode
• AC + DC mode
• Sensing
• Regulation adjustment
• Average voltage value measurement
• Average current value measurement
NOTE
• The power line abnormality simulation function available in
single-phase, three-wire operation differs partially in its specifications from that available in single-phase operation. For
more information on this, see “Chapter 11 Specifications” of
the PCR-LA AC Power Supply Operation Manual.
