equipment, then contact your dealer or our distributor.

III
USING THE PRODUCT SAFELY
CAUTION
■ Caution about Installation Condition
- If this product is used in a place with much electrical noises, it may malfunction. Be sure to ground this
product using the GND terminal of the 3-core power cable or the GND lead wire of a 3P-2P conversion
plug, if used, when it is necessary to use this product in a place with much electrical noises.

exceeded. Input or output over the maximum rating may result in damages to the product.
■Before Long-Term Unemployment
- If the product is to be unused for a long period of time, disconnect the AC power cable from the
AC outlet.
■Calibration
- The product has been inspected under strict quality control before shipment. It is, however, subject
to change in the performances due to aged deterioration of parts. To maintain its performances for
long, we recommend that it should be calibrated periodically. For calibration, please contact your
dealer or our distributor.
■Daily Maintenance
- Do not use thinner, benzine or other solvents to clean the case, panels, knobs, etc. of the
product. Such solvent may separate the coating or deteriorate the resin surface.
- Clean the case, panels, knobs, etc. lightly with soft cloth moistened with neutral detergent.
- Before cleaning the product, disconnect the power plug from the AC outlet. Be careful not
to put water, detergent or other foreign matters into the product.

IV
USING THE PRODUCT SAFELY
CAUTION
■ Input/output terminal
Maximum input to the input terminals is specified to prevent the product from being damaged.
Do not supply input, exceeding the specifications that are indicated in the "Rating" or "Caution on
use" column in the user's guide of the product. Otherwise, a product failure is caused.
Also, do not supply power to the output terminals from the outside.
Otherwise, a product failure is caused.
■When the product is left unused for a long time
Be sure to remove the power plug from the outlet.
(Calibration)
Although the performance and specifications of the product are checked under strict quality control
during shipment from the factory, they may slightly change because of secular changes in its parts.
It is recommended to periodically calibrate the product so that it is used with its performance and
specifications stable. For consultation about the product calibration, call the dealer or the
company or each sales office where you bought the product.
(Daily maintenance)
When you clean off the dirt of the product covers, panels, and knobs, avoid solvents such as
thinner and benzene. Otherwise, paint may peel off or the resin surface may be affected.
To wipe off the covers, panels, and knobs, use a soft cloth with neutral detergent in it.
During cleaning, be careful that water, detergents, and other foreign matters do not get into the
product.
If a liquid or metal gets into the product, an electric shock and fire are caused.
During cleaning, remove the power cord plug from the outlet.
Use the product correctly and safely, observing the above warning and caution items.
Because the user's guide indicates caution items even in individual items, observe those
caution items to correctly use the product.
If you have questions or comments about the content of the user's guide, call the
company's sales office.

1. PW-A SERIES
1-1. About This Manual
This manual applies to the following PW-A series power supply units and optional interface units.
PW-A series:
PW18-1.8AQ，PW18-1.3AT，PW18-3AD，PW36-1.5AD
PW18-3ADP，PW18-2ATP，PW16-5ADP，PW8-3ATP
PW26-1AT，PW36-1.5ADP，PW18-1.3ATS，PW26-1ATS
PW8-3AQP、PW16-2ATP、PW24-1.5AQ、PW8-5ADPS
Optional interface units for the PW-A series:
IF-41RS，IF-41GU，IF-41USB
Note：The IF-41 series are compatible with all models of the PW-Apower supply unit series shown
above. The previous IF-40 series are not compatible with the PW8-3AQP, PW16-2ATP,
PW8-5ADPS and PW24-1.5AQ.
Use the IF-41 series, not IF-40 series, for the PW8-3AQP, PW16-2ATP, PW8-5ADPS and
PW24-1.5AQ.
“YB” models with built-in factory options
1-2. Outline of Product
The PW-A series are dropper type multi-output DC stabilized power supply units. With the tracking,
delay and four-point preset functions, each unit has a wide variety of applications. The optional
interface boards IF-41GU, IF-41RS and IF-41USB are built in the PW-A series and interface with
computers. Each PW-A series power supply unit connected with a computer is connectable with
another PW-A series power supply unit through the local bus, allowing construction of an intelligent
power supply system. It is possible to control all power supply units in the system and read back the
current and voltage values from the computer.
1-3. Features
1-3-1. PW-Apower supply unit
- The tracking function may vary the voltage and current of each channel at he same ratio (or by an
absolute value). It may be set for each output. It is possible to vary all outputs simultaneously.
- The delay function may turn on or off a specific channel after a delay of specified time in the
multi-output mode. It is possible to set the delay time of each channel independently between 0 to
10 seconds.
- With a CPU and four preset memory units, the PW-Apower supply unit may store preset voltage
and current of each channel. This function enables easy switching of the voltage (or current).
- The output voltage and current are displayed on seven-segment, four-digit red LED indicators. Fine
adjustment functions are provided for accurate setting.
- It is possible to turn on or off each channel independently. The LED clearly indicates in which
status, CV or CC, each channel is.
- It is possible to select PRESET 1 to PRESET 4, turn on or off MAIN OUTPUT key, detect an OHA
alarm and input an alarm through the external contacts.
- The YB option is available. This factory option lowers the output voltage quickly when output is
turned off with no load or light load. "YB" is added to the product code of a model with this option.
(Example: PW18-1.8AQYB)
- The PW18-1.3ATS and PW26-1ATS have remote sensing terminals in the C channel.
The PW8-5ADPS have remote sensing terminals in both channels.
Use the remote sensing terminal to compensate for voltage drop caused by the wires.

2
1-3-2. IF-41RS（Option）
- The PW-A power supply unit with a built-in IF-41RS is possible to remote-control when it is
connected with a computer by RS-232C. The computer controlling the PW-Apower supply unit is
called the master unit, and the controlled PW-Apower supply unit is called the slave unit. It is
possible to connect a maximum of four slave units, which are connected with one another with
modular cables.
- It is also possible to specify equipment other than a computer as the master unit. If the PW-A
power supply unit is specified as the master unit, operating the master unit causes the other four
PW-Apower supply units to execute the same operation. (Master operation)
- It is also possible to specify the GP-620 (our GP-IB adapter) or RT-63 (our remote controller) as
the master unit, which may remote-control the PW-Apower supply unit.
- The PW-A power supply unit is compatible with the PWR series (our power supply unit). It is
possible to construct a system containing PWR series power supply unit(s).
1-3-3. IF-41GU（Option）
- The IF-41GU is an optional board, which features higher transmission rate than the IF-41RS and
may control more power supply units simultaneously.
- It is connected with a computer through GP-IB or USB.A maximum of fourteen or thirty-two units
may be connected directly with a computer through GP-IB or USB, respectively.
- It is also possible to construct a large-scale system if thirty-one PW-Apower supply units are
connected with a PW-A power supply unit directly connected with a computer using two sets of
twisted pair cables and these units are remote-controlled.
1-3-4. IF-41USB（Option）
- The IF-41USB is an option board with the USB connector and local bus, which have the same
functions of those of the IF-41GU.
- It allows the user to construct a system at lower cost than using the IF-41GU.
