USING THE PRODUCT SAFELY

■Preface

To use the product safely, read instruction manual to the end. Before using this product,

understand how to correctly use it. If you read the manuals but you do not understand

how to use it, ask us or your local dealer. After you read the manuals, save it so that

you can read it anytime as required.

■Pictorial indication

The manuals and product show the warning and caution items required to safely use the

product. The following pictorial indication is provided.

Pictorial

indication

Some part of this product or the manuals may show this

pictorial indication. In this case, if the product is

incorrectly used in that part, a serious danger may be

brought about on the user's body or the product. To use

the part with this pictorial indication, be sure to refer to the

manuals.

If you use the product, ignoring this indication, you may get

killed or seriously injured. This indication shows that the

warning item to avoid the danger is provided.

If you incorrectly use the product, ignoring this indication,

you may get slightly injured or the product may be

damaged. This indication shows that the caution item to

avoid the danger is provided.

Please be informed that we are not responsible for any damages to the user or to the

third person, arising from malfunctions or other failures due to wrong use of the product

or incorrect operation, except such responsibility for damages as required by law.

USING THE PRODUCT SAFELY

■Do not remove the product's covers and panels

Never remove the product's covers and panels for any purpose.

Otherwise, the user's electric shock or fire may be incurred.

■Warning on using the product

Warning items given below are to avoid danger to user's body and life and avoid the

damage or deterioration of the product. Use the product, observing the following

warning and caution items.

■Warning items on power supply

●Power supply voltage

The rated power supply voltages of the product are 100, 120, 220 and 240VAC. The

rated power supply voltage for each product should be confirmed by reading the label

attached on the back of the product or by the “rated” column shown in the instruction

manual. The specification of power cord attached to the products is rated to 125VAC

for all products which are designed to be used in the areas where commercial power

supply voltage is not higher than 125VAC. Accordingly, you must change the power

cord if you want to use the product at the power supply voltage higher than 125VAC. If

you use the product without changing power cord to 250VAC rated one, electric shock

or fire may be caused. When you used the product equipped with power supply

voltage switching system, please refer to the corresponding chapter in the instruction

manuals of each product.

●Power cord

(IMPORTANT) The attached power cord set can be used for this

device only.

If the attached power cord is damaged, stop using the product and call us or your

local dealer. If the power cord is used without the damage being removed, an

electric shock or fire may be caused.

●Protective fuse

If an input protective fuse is blown, the product does not operate. For a product with

external fuse holder, the fuse may be replaced. As for how to replace the fuse, refer

to the corresponding chapter in the instruction manual. If no fuse replacement

procedures are indicated, the user is not permitted to replace it. In such case, keep

the case closed and consult us or your local dealer. If the fuse is incorrectly

replaced, a fire may occur.

USING THE PRODUCT SAFELY

■Warning item on Grounding

If the product has the GND terminal on the front or rear panel surface, be sure to ground

the product to safely use it.

■Warnings on Installation environment

●Operating temperature and humidity

Use the product within the operating temperature indicated in the “rating” temperature

column. If the product is used with the vents of the product blocked or in high

ambient temperatures, a fire may occur. Use the product within the operating

humidity indicated in the “rating” humidity column. Watch out for condensation by a

sharp humidity change such as transfer to a room with a different humidity. Also, do

not operate the product with wet hands. Otherwise, an electric shock or fire may

occur.

●Use in gas

Use in and around a place where an inflammable or explosive gas or steam is

generated or stored may result in an explosion and fire. Do not operate the product

in such an environment. Also, use in and around a place where a corrosive gas is

generated or spreading causes a serious damage to the product. Do not operate the

product in such an environment.

●Installation place

Do not insert metal and inflammable materials into the product from its vent and spill

water on it. Otherwise, electric shock or fire may occur.

■Do not let foreign matter in

Do not insert metal and inflammable materials into the product from its vent and spill

water on it. Otherwise, electric shock or fire may occur.

■Warning item on abnormality while in use

If smoke or fire is generated from the product while in use, stop using the product, turn

off the switch, and remove the power cord plug from the outlet. After confirming that

no other devices catch fire, ask us or your local dealer.

USING THE PRODUCT SAFELY

■Input / Output terminals

Maximum input to terminal is specified to prevent the product from being damaged. Do

not supply input, exceeding the specifications that are indicated in the "Rating" column in

the instruction manual of the product. Also, do not supply power to the output terminals

from the outside. Otherwise, a product failure is caused.

■Calibration

Although the performance and specifications of the product are checked under strict

quality control during shipment from the factory, they may be deviated more or less by

deterioration of parts due to their aging or others.

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,

ask us or your local dealer.

■Daily Maintenance

When you clean off the dirt of the product covers, panels, and knobs, avoid solvents

such as thinner and benzene. Otherwise, the paint may peel off or 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, or 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 instruction manual indicates caution items even in individual items, observe

those caution items to correctly use the product.

If you have questions or comments about the manuals, ask us or E-Mail us.

1. GENERAL

The PD-AD series are compact DC power supplies regulated by phase control. They have

sufficient reliability and accurate electrical characteristics and are suitable for research,

experiments, aging of many hours, and for control, etc. They are provided also with means

of protection and remote control. They are designed totally for the ease of use.

2. FEATURES

○ The size is compact owing to the built-in phase-controlled preregulator.

○ Characteristics of voltage regulation and against noises in-cluding ripples are very

good.

○ Both voltage and current vary little with temperature.

○ The output voltage and output current may be changeable in small steps with a

potentiometer turnable as many as ten positions.

○ The V／I CHECK switch provided permits to check the preset values of voltage and

current even during operation.

○ The OUTPUT switch turns on and off the output.

○ The use of the external contact allows the output to be turned on and off from outside.

○ Protection is complete from overvoltage, overcurrent, and excessive temperature rise.

The OVP CHECK function provided permits to preset the overvoltage protection level

and check the preset level during operation.

○ Master / slave control is possible by series and parallel connections.

○ The output voltage and current may be remote-controlled using an external resistance

or external signals.

○ Rapid transient characteristics are good.
