When using this product, give due consideration to the precautionary notes described below
and ensure a safe design. Inappropriate use may result in electric shock, injury or fire.
Caution
Precautionary Notes Regarding the Use of This Inverter
This product is designed for the lighting of a Cold Cathode Fluorescent Lamp.
Do not use it with any other load.
Store this product under the conditions defined in the specification document.
Do not store this product in an environment where dust, dirt or corrosive gas(salt,acid,base, etc.) is present.
This product is subject to high voltage. If there is a possibility that the user may touch the product,
provide a proper indication in order to draw the user's attention.
This product is designed for use with general electronic equipment.
If it is to be used with medical equipment that directly affects human life or for the control of
transportation equipment to which passengers entrust their lives, provide thorough fail-safe measures.
lf this product use for in-vehicle or always vibrated place,please consult us before using.
Avoid using this product under high temperatures or high humidity or in an environment in which
dust, dirt or any corrosive gas (salt,acid,base, etc.) is present.
Also,be careful not to allow the formation of dew condensation. It may result in damage or electric shock.
If the product does not have a built-in protective circuit (circuit breaker, fuse, etc.),
it is recommended that a fuse be used at the input stage to prevent the generation of
smoke or fire in the event of a malfunction.
Even when the product has a built-in protective circuit (circuit breaker, fuse, etc.),
the circuit may not function properly due to inappropriate operating conditions or power-supply capacity.
It is recommended that an appropriate protective circuit (circuit breaker, fuse, etc.)
be provided separately from the built-in circuit.
Use the product only within the specified input voltage, output power, output voltage
and operating temperature ranges. Exceeding these values may result in damage, etc.
Provide a measure for the prevention of surge voltage due to lightning, etc.
Abnormal voltage may result in damage, etc.
To prevent problems arising from short-circuiting of the high-voltage section,
provide appropriate measures to prevent the entry of foreign substances following installation.
This product is not designed to provide resistance to radiation.
Please fix the inverter by using all the mounting holes to protect the inveter against vibration and shock.
Ripples could be superimposed on the voltage and the current in the input source connected to the inverter ,
depending on the impedance in the input source, wiring, etc.
When you select an input source, please check waveforms, etc on the final set.
Warning
This product is subject to high voltage. Do not touch it while the power is on.
Failing to do so may result in electric shock.
Handling Precautions
This product uses thin wires. Observe the following precautions and handle it with care so
as not to cause wire breakage. Broken wire may result in damage, etc.
Do not stack multiple products on top of one another.
Do not allow the product to come in contact with tools, etc.
Do not apply excessive stress during installation.
It may cause chipping and cracking,resulting in damage, etc.
Provide clearance between the high-voltage section of this product and the frame body on which the product
is installed and also the conductor section as per listed on page 2 , [1] ”Outline” .
Please do not use the product, when dropping it, since there is a possibility of the parts damage.
Please confirm abnormality is not found in the product enough when using it by any chance.

Features
This inverter is for two lamps. It has Dimmi ng function(PWM System) and Remote function.
This product has shutdown function.
It prevents from keeping generating the high voltage wh en the lamps open.(Refer Note. 4-4.)
With lamp failure det ector.
Normal Operation : CN1-6=0V
Some Lamps Open : CN1-6=5V
Select the way of dimming (between CN1-6 and CN1-7)
1. Insert a potentiometer (0-50k)
2. Apply the voltage (0-2.5V)
The high-voltage area (terminals and patterns) is coated with silicone so as to avoid the defects caused by dust.
       ・This product is conformity to RoHS directive.
        (※)Conformity to RoHS Directive:This means that, in conformity with EU Directive 2002/95/EC,
        lead, cadmium, hexavalent chromium, and specific bromine-based flame retardants, PBB

For circuit connection, please prefer to test circuit diagram [4].
Please use minimum of 3mm clearance (all directions) between inverter high voltage area and any
conductors.
Please refer to mechanical drawing for marking of high voltage area.
Open voltage (strike voltage) is measured across the transformer secondary winding at no load as the
reading at
the output connector would be less than the actual value.

If the start up voltage falls below Cold Cathode Tube strike voltage, the CCFL will not light up easily specially at
lower ambient temperature. Please review mounting instruction to avoid any abnormal operation due to
coupling/leakage capacitance of inverter high voltage are a to any surrounding conductor.
Please check your lamp characteristic for minimum operational current and set the limit point in your design to
avoid flickering and/or abnormal operation.
For proper operation of circuit protection (fuse or IC PROTECTOR),Please use mi nimum of 2.5A capacity for input
power supply.
For proper operation: Don't connect the out put VLOW(CN2-4) terminal to the input GND (CN1-3,4).

The test circuits added 7.5pF capacitor across the load resistor for LCD back light stay capacitor.Note 2-1.
Impedance from the power source or connectio n can cause ripple at the input voltage/current.
This products includes an internal fuse rated at 1.25A. Please make sure that the ripple from the input current
does not go above 1.25A.
