■Product Overview
Product Overview
This product is a compact output variable type high voltage power supply (voltage transformer) with
anomaly detection circuit, intended for supplying high voltage AC power to applicable VESSEL
ionizers, which are designed to eliminate static electricity from charged items.
This product uses 24 VDC input. Please use the dedicated AC adapter. The dedicated AC adapter
supports a wide range of input voltage from single phase 100 VAC to 240 VAC, and 50 to 60 Hz. If
using DC power supply for machinery equipment, etc., connect a 24 VDC ± 10% 1 A power supply.
In this case, connect the 0 V side to ground.
Product Features
●AC Output Voltage Adjustment Function
This power supply can adjust AC output voltage within the range of 3.5 kV to 7 kV. For this reason,
this can be used with various VESSEL ionizers.
●DC Output Voltage Adjustment Function
This power supply can output a variable DC output voltage between -150 VDC and +550 VDC on
top of the AC output voltage. The DC output is for regulating ion balance. It cannot be used as a
DC power supply. Furthermore, depending on the VESSEL ionizers connected, ion balance
adjustment may not be available.
●Safety/Anomaly Detection Circuit
This power supply incorporates a safety circuit that will automatically shut off the output when a
high voltage short circuit is detected.
●Power Indicator Light
The power indicator light employs a high-brightness blue LED with excellent visibility, so that you
can easily see whether the power is on or off from far away. This power indicator light goes out
when an anomaly is detected.
●High Voltage Output Confirmation Function
The output monitor terminals emit a voltage is 1/1000th of the high output voltage. The high
voltage output can be easily read by connecting a common digital multimeter or tester to these
monitor terminals in AC voltage measurement mode.

■Installation
When using an external power supply
Instead of using the included AC adapter, power can be
supplied externally.
Connect wiring using a MOLEX connector, as shown in the figure.
Please be sure to connect to ground. Otherwise a ground wire
may be connected to the ground terminal on the rear of the unit.
Please shut off the external power supply when stopping
operation.
Output monitor terminals
You can easily check the AC high voltage output by connecting a digital
multimeter or tester (1 MΩor more of impedance) to the output monitor
terminals (MONITOR) on the side of the unit.
(A tester pin with an outer diameter of 2 mm will fit.)
1. Put the tester, etc. in AC voltage measurement mode, and connect it to
the output monitor terminals (MONITOR). Since there is no polarity, it
doesn't matter which side you connect to the COM terminal.
2. Once the power is turned on for the unit, a value that is 1/1000th that
of the AC high voltage output (AC 4 to 7 V) will be displayed on the tester. The high voltage output
voltage will be the value which is multiplied by 1000 of the displayed value.
Ex.: If the tester shows 4.2 V, the high voltage output will be 4.2 kV
CAUTIONS
CAUTIONS
• Be sure to conduct measurements with the tester in AC voltage
measurement mode.
• Do not apply a voltage to the output monitor terminals as it may lead
to failure.
REMEMBER • Do not short the output monitor terminals or connect them to ground.
It may lead to failure.
Output voltage adjustment
Make sure to carry out output adjustment while the ionizer is disconnected. When the product has
been shipped together as a set with an ionizer, output voltage setting/adjustment has normally been
carried out already; so this procedure is not necessary.
After installation work is complete, double-check the output voltage by connecting a tester, etc. in AC
voltage measurement mode to the output monitor terminals while the antistatic electrode is
connected. Make adjustments if necessary.
AC output voltage switching
This product can switch between AC output voltages.
Remove the top cover and operate the internal selector
switch and adjustment knobs.

CAUTIONS
CAUTIONS
• Set to a suitable output voltage for each ionizer. The proper voltage for
each ionizer can be found in the instruction manual for that model.
Using the wrong voltage can lead to failure of both the unit and the
ionizer.
• Because output voltage adjustment is carried out while the unit is
energized, it is very dangerous. It should only be conducted by an
operator who has proficiency in handling of electric products, including
electric wire.
PROHIBITED
• You may open the top cover of this product in order to adjust the
adjustment knob, but do not manipulate anything other than the
aforementioned output selector switch or output adjustment knobs.
Doing so may lead to accidents or malfunction.
• The top cover is connected to the unit by a ground wire. Do not remove
or damage this ground wire.
• After making adjustments, be sure to put back the top cover. Do not use
the product without the top cover.
Anomaly Detection Circuit
For safety, the anomaly detection circuit automatically stops high voltage output when high voltage is
leaked to any part of the unit other than the electrode.
Anomaly detection external output (C-contact relay output, 3-pin terminal)
This product includes contacts for use with external alarm devices such as error lamps, buzzers, etc.
when anomalies are detected. (Because they are zero-voltage, a separate power source is
required.)
There is a few hundred millisecond delay after the power switch is turned ON before the transformer
reaches its normal value. So please include a 1 second time lag in external circuits such as PLCs.
(Please include a 1 second time lag on the PLC side after the input power source is turned ON
during which anomalies are not detected.)

conditions.
Wiring the high voltage cable
VESSEL ionizers electrodes that can be connected to this product have either a CON-4 or CON-7
special purpose high voltage connector attached to the end of the high voltage cable. We offer
capacitive coupling type, resistance connection type, or direct connection type ionizers, and the type
of connector varies depending on the type of ionizer.
The maximum load that can be connected to this product, in the case of the SSB bar series ionizer,
is a bar with a total overall length of 5 m. Details about our other ionizers can be found in the
instruction manual for each model. Using this product with loads in excess of the maximum load
radically shortens the life of the unit, electrode, and high voltage cable. And if the load is too large,
the anomaly detection function will be activated as soon as the power is turned on, and you will not
be able to use the product.
After installing the ionizer, high voltage cable, and ground wire, firmly tighten and connect the high
voltage connector at the end of the high voltage cable to the ceramic output terminals on the unit
(there are 2) by hand. (Do not use tools such as pliers.) If the high voltage cable is shielded, be sure
to connect the ground wire on the end of the cable, to the ground terminal on the unit.
* For precautions on connecting the high voltage cable, please read the instruction manual for the
corresponding ionizer.

replacement, turn the power switch [ON].
〇Returns to operational status.
* If the anomalous state has not been eliminated, it will once again change to an error display.
CAUTION
REMEMBER • When the product will not be used for an extended period of time, unplug
the AC cable from the outlet.

12
■Operation
CAUTION
CAUTION
• Malfunctions may occur due to electrical noise during momentary power
failures, lightning strikes, high-capacity motor startup, etc. If the product
shuts down abnormally for one of these reasons, perform a reset. If this
occurs frequently, use the anomaly detection sensitivity adjustment (P.10)
to set the sensitivity to LOW.
• When performing a reset using the power switch, once you have turned
the power OFF, wait 10 seconds or more before turning it ON again.
• If the power is repeatedly turned ON and OFF in short cycles, a load will
be placed on the internal transformer, etc. and shorten the life of the
device. Try to leave 5 minutes or more for each continuous recurring cycle
between ON and OFF.
Ion balance adjustment
This product can enables to adjust ion balance.
If the balance of positive and negative ions produced by the electrode is off, the static electricity
cannot be removed, or instead, it is produced. This product can output DC voltage in addition to the
AC high voltage output. By manipulating this DC voltage, the ion balance can be adjusted.
There is an adjustment knob on the other side of the connectors.
Turning the knob labeled (ION BALANCE ADJ) to the left or right
increases or decreases the DC voltage, adjusting the amount of
positive and negative ions produced by the ionizer.
Carry out adjustments by measuring the actual ion balance with
a CPM (charged plate monitor) etc.
IF THE PRODUCT HAS BEEN PURCHASED AS A SET WITH AN IONIZER, THE ION BALANCE
HAS BEEN ADJUSTED BEFOREHAND BASED ON PRE-DETERMINED STANDARD USAGE
CONDITIONS. BECAUSE THE ION BALANCE WILL VARY DEPENDING ON INSTALLATION
DISTANCE, USE OF COMPRESSED AIR, ETC., IT IS RECOMMENDED TO PERFORM ION
BALANCE ADJUSTMENT BASED ON ACTUAL USAGE CONDITIONS.
CAUTION
CAUTION
• If the ion balance is an important factor in the location where this product is
used, use with just 1 ionizer connected to the unit. The ion balance cannot
be individually adjusted for each ionizer when multiple models are
connected to the same power supply unit. For example, if 2 ionizers are
connect to the same unit, and the ion balance is adjusted for one of the,
ionizers the ion balance of the other ionizer may not be as expected.
• Ion balance adjustment cannot be carried out for "SSB bar series".
For other ionizers, please consult the instruction manual for each model.

13
