SAFETY
1. BE SURE TO GROUND!!
Be sure to ground the power supply unit before use.
2. DO NOT TOUCH ANY HIGH VOLTAGE TERMINALS!!
Do not operate the power supply unless who is familiar with the operation process, the hazards
of high voltage, and the treatment for the electrical shock is present.
3. UNDERSTAND THE HAZARDS OF HIGH VOLTAGE!!
In case you let somebody operate the power supply for you, must be sure that he/she fully
understands the hazards of high voltage and the areas where never can be touched.
4. CUT OFF THE POWER BEFORE TOUCH THE UNIT!!
Cut off the power, and check that the power is OFF, before you touch the power supply.
Capacitors in the output circuit are still charged and dangerous even after the power has been
cut off.Discharge all remaining high voltage by grounding them.
5. DISCONNECT THE INPUT LINES(AC LINES) !!
In case you need to touch the inside of the power supply following instruction manual, cut off
the power and disconnect the input lines(AC lines), and ground all the capacitors and high
voltage section.
Don’t remove the case or touch the inside of power supply unless so instructed in the
instruction manual.
6. OPERATE THE POWER SUPPLY WITH YOUR RIGHT HAND!!
In order to avoid the electric shock to your important organs, operate the power supply with
your right hand and keep your left hand off from the power supply.
This power supply unit generates high voltage and energy.
Electric shock may lead to death or serious injury.
Be sure to follow the instructions below and handle the unit with caution.

achieving its performance but also
causes deterioration of parts leading to
smoking or burning.
Do not wipe the unit with chemicals
(such as thinner) or wet cloth.
It may allow water inside leading to
electric shock, electrical leak or burning.
Do not cover the vent holes of the unit.
Vent holes are provided to prevent
elevation of temperature inside.
Covering them not only hampers the unit
from achieving its performance but also
causes deterioration of parts, which may
generate smoke or set fire.
Do not install the unit and the remote
controller in a place subject to direct
cold air. Condensation may lead to
electrical leak/burning.
Do not install the unit in a place subject
to corrosive gas or liquid (such as a
place where chemicals are handled).
Deterioration of parts may cause
generation of smoke or burning.

(1) RESCUE
FREE VICTIM FROM CONTACT WITH LIVE CONDUCTOR QUICKLY.
AVOID CONTACT WITH FITHER LIVE CONDUCTOR OR VICTIM’S BODY.
Shut off high voltage at once and ground circuit. If high voltage cannot be turned off
quickly, ground circuit.
An ax with a dry wooden handle may be used to cut high voltage line.
Use extreme caution to avoid resulting electric flash.
If circuit cannot be broken or grounded, use a dry board, dry clothing, or other
nonconductor to free victim.
(2) SYMPTOMS
NEVER ACCEPT ORIDNARY AND GENERAL TESTS FOR DEATH.
Symptoms of electric shock may include unconsciousness, failure to breathe, absence of
pulse, pallor, and stiffness, as well as severe burns.
WHENEVER VICTIM IS NOT BREATING PROPERLY, GIVE ARTIFICIAL RESPIRATION.
(3) TREATMENT
START ARTIFICIAL RESPIRAITON IMMEDIATELY.
Perform artificial respiration at scene of accident, unless victim’s or operator’s life is
endangered. IN THIS CASE ONLY, remove victim to safe location nearby, if new location
is more than few feet away, give artificial respiration while victim is being moved.
After starting artificial respiration, continue without loss of rhythm for at least FOUR
HOURS, or until victim is breathing without help.
If you have to change operators while giving artificial respiration, do so without losing
rhythm of respiration.
(4) AFTER VICTIM REVIVES
Be prepared to resume artificial respiration, as he may stop breathing again.
When victim is CONPLETELY CONSCIOUS, give him a stimulant (NOT AN ALCOHOLIC
DRINK) such as teaspoonful of aromatic spirits of ammonia in a small glass of water, hot
coffee, or hot tea.
Keep victim warm and lying down until he has been conscious for at least fifteen minutes.
First-aid procedures to be implemented in case of electrical shock

ⅴ
1.POSITION VICTIM
Place victim in face-upward position an kneel close to his ear.
2.CLEAR THROAT
Turn head to one side quickly wipe out any fluid, mucus, or
foreign body from mouth and throat with fingers.
3.OPEN AIR PASSAGE
Tilt head back and extend neck to open air passage.
4.LIFT JAW FORWARD
Ice thumb in victim’s mouth and grasp jaw firmly. Lift jaw
forward to pull tongue out of air passage. Do not attempt to
hold or depress tongue.
5.PINCH NOSTRILS CLOSED
With other hand pinch nostrils closed to prevent air leak.
6.FORM TIGHT SEAL WITH LIPS
Rescuer’s wide-open mouth completely surrounds and seals
open mouth of victim,
This is not a kissing or puckered position-mouth of rescuer
must be wide-open,
7.BLOW
Exhale firmly into victim’s mouth until chest is seen to lift.
This can be seen by rescuer without difficulty.
8.REMOVE MOUTH AND INHALE
During this time, rescuer can hear and feel escape for air from
lungs.
Readjust position if air does not flow freely in and out of victim’s
lungs.
Continue at a rate of 12 to 20 times per minute.
Breathing should be normal in rate with only moderate increase
in volume so that rescue breathing can be continued for long
periods without fatigue. Do not breathe too forcibly or too
large a volume if victim is an infant or small child.
8.Remove mouth and
inhale

1-4 Points to be careful about in handling and care
WHEN TOUCHING LOAD AFTER TURNING OFF A HIGH TENSION
1. Make the setting of an output voltage to zero (0). Turn off the INTLK switch.
2. Turn the input voltage (24 VDC) OFF.
3. Earthling an output for longer than 10 seconds, check and confirm that the voltage is zero
at another high tension voltmeter. It is especially dangerous that the load is capacitate
or a long cable is attached there to.
4. Make it a rule to touch load with right hand.
How to GROUND
・ For safe operation, be sure to ground the ground terminal of power supply at one point
on the ground.
If the Load frame is not grounded
If the Load frame is grounded
・ Be sure to complete grounding as shown above. Inadequate grounding may lead to
electric shock of damage to the power supply unit, which is dangerous.
・ If there is a possibility of development of a short-circuiting of load or discharging, make
larger and shorter the grounding conductor.
IN ORDER TO INSURE SAFETY THE GROUND
TERMINAL SHOULD BE EARTHED AT ALL TIME.

FOR SAFER OPERATION
1. Laying an insulation plate which can withstand the voltage to be used on the floor on
which an operator stands, carry out the operation. If done so, it will be comparatively
safe.
2. When operating a power supply and load, do so with right hand with left hand put in the
pocket, taking care not to touch other objects.
3. After turning off the voltage (even if a long time has lapsed after turning off), if you
touch load, be sure to earth the output longer than 10 seconds.
1-5 What to do before calling for service
・ In case no output voltage is generated.
1. Check whether or not a specified voltage has been inputted.
・ Input Voltage +24Vdc ±10%
・ Control voltage 0 – 10V at the time of controlling over external voltage.
・ Control voltage 0 – 10V at the time of controlling over external current.
・ In case a discharging noise is generated near a high voltage output block :
1. Check whether or not plug block of the high voltage connector (part shown with an
arrow mark hereunder) is stained. If used with plug stained, a discharging phenomenon
will develop sometimes inside connector sometimes. Wiping off stains with such liquids
as alcohol, dry it fully and use it.

GROUNDING OF ALL HIGH VOLTAGE EQUIPMENT IS ESSENTIAL.
CAUTION
ALWAYS OPERATE THE UNIT WITH THE COVER ON.
3-1 Overview
This product is a compact module power supply unit developed for small X-ray tubes.
High voltage supply and filament supply are integrated and a tube current control function is
provided.
3-2 Operation
1. Make sure that the specified connection (see 1-4 [Grounding]) is made with this unit before
starting operation. For ensuring safety, be sure to ground the GROUND terminal of the
unit.
2. Use the connector supplied to connect the power supply unit, filament, monitor and control
system.
For the control system, provide the J5 (D-sub 9-pin) connector as shown below.
Output voltage control
Local: connect between③-④ (set with the kV ADJ trimmer).
Remote: input the control voltage between③-⑨ (GND).
Output current control (tube current control)
Local: connect between⑥-⑦ (set with the mA ADJ trimmer).
Remote: input the control voltage between⑥-⑨ (GND).
3. Make sure that INTLK is turned OFF.
(Note that High Voltage and Filament are output by next operation if INTLK is turned ON.)
4. Input 24 VDC as the input voltage. The PWR ON (green) and HV OFF (yellow) LEDs are
illuminated.
