NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from use of a product described herein or any other liability arising from use of such application. No license, express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or of others. While NEC Corporation has been making continuous effort to enhance the reliability of its products, the possibility of failures cannot be eliminated entirely. To minimize risks of damage to property or injury to person arising from a failure in an NEC product, customers must incorporate sufficient safety measures in their design, such as redundancy, fire-containment and anti-failure features. NEC products are classified into the following three quality grades: " S t a n d a r d " , " S p e c i a l " , " S p e c i f i c " The "Specific" quality grade applies only to applications developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a product depend on its quality grade, as indicated below. Customers must check the quality grade of each application before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Military systems, aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems (medical equipment, etc.) and any other equipment The quality grade of this product is "Standard" unless otherwise specified in this document. If customers intend to use this product for applications other than those specified for "Standard" quality grade, they should contact NEC Corporation sales representative in advance. Anti-radioactive design is not implemented in this product. 65PWB31 DATA SHEET EN0560EJ1V0DS00 3 CONTENTS INTRODUCTION.......................................................................................................................................... 2 1.

Unit Remarks Input voltage Power supply voltage VDDB 4.75 5.0 5.25 V - Input current Power supply current IDDB - 900 1000 mΑ VDDB = 5.0V Note1 Output voltage Open lamp voltage VO 900 - - Vrms Starting voltage for lamp Output current LCD lamp IL - 5.0 - mArms per one lamp Oscillation frequency FO 51.0 55.0 59.0 kHz Luminance control frequency for LCD lamp FL 250 270 290 Hz - Note1: The power supply lines (VDDB and GNDB) occurs large ripple voltage while luminance control of LCD lamps. There is the possibility that the ripple voltage produces acoustic noise and signal wave noise in audio circuit and so on. Put a capacitor (5,000 to 6,000µF) between the power source lines (VDDB and GNDB) to reduce the noise, if the noise occurred in the circuit. 2.4 FUSE Fuse Parameter Type Supplier Rating Fusing current Remarks 2.0A VDDB KE20 Daito Communication Apparatus Co., Ltd. 24V 4.0A Note1 Note1: The power supply capacity should be more than the fusing current. If the power capacity is less than the fusing current, the fuse may not blow for a short time, and then nasty smell, smoking and so on may occur. 65PWB31 DATA SHEET EN0560EJ1V0DS00 6 2.5 CONNECTIONS AND FUNCTIONS FOR INTERFACE PINS CN1 socket (Inverter side): IL-Z-6PL-SMTY (Japan Aviation Electronics Industry Limited (JAE)) Adaptable plug: IL-Z-6S-S125C3 (Japan Aviation Electronics Industry Limited (JAE)) Pin No. Symbol Function Remarks 1 GNDB Backlight ground - 2 GNDB Backlight ground - 3 VDDB Power supply - 4 VDDB Power supply - 5 BRTL Luminance control input Note1 6 BRTH Luminance control input Note1, Note2 Note1: A way of luminance control by a variable resistor.

PRECAUTIONS 3.1 MEANING OF CAUTION SIGNS The following caution signs have very important meaning. Be sure to read "3.2 CAUTIONS" and "3.3 ATTENTIONS", after understanding this contents! ! This sign has the meaning that customer will be injured by himself or the product will sustain a damage, if customer has wrong operations. This sign has the meaning that customer will get an electrical shock, if customer has wrong operations. This sign has the meaning that customer will be injured by himself, if customer has wrong operations. 3.2 CAUTIONS ∗∗∗∗ Do not touch the inverter while the inverter is working, because there is a danger that customer will get an electric shock. ∗∗∗∗ Do not remove the inverter protection sheet, because there is a danger that customer will get an electrical shock. ∗∗∗∗ Be sure to wait some time after turning power OFF before starting replacement work, because the inverter is charged at a high voltage after working. ∗∗∗∗ Be sure to wait some time after turning power OFF before starting replacement work, because the inverter is hot after working. ∗∗∗∗ Do not shock the inverter, because there is a danger of breaking. 3.3 ATTENTIONS ! 3.3.1 Handling of the product x Take hold of both ends without touch the mounting parts when customer pulls out products from packing box. If customer touches it, products may be broken down or out of adjustment, because of stress to mounting parts. y Take the measures of electrostatic discharge such as earth band, ionic shower and so on, when customer deals with the product, because products may be damaged by electrostatic. z Do not push-pull the interface connectors while the product is working, because wrong power sequence may break down the product. { Do not hook cables nor pull connection cables such as lamp cable and so on, for fear of damage. 65PWB31 DATA SHEET EN0560EJ1V0DS00 8 3.3.2 Environment x Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases. Keep the product in antistatic pouch in room temperature, because of avoidance for dusts and sunlight, if customer stores the product. y Do not operate in high magnetic field. Circuit boards may be broken down by it. 3.3.3 Other x All GNDB and VDDB terminals should be used without a non-connected line. y Do not disassemble a product or adjust volume without permission of NEC Corporation. z Pack the product with original shipping package, because of avoidance of some damages during transportation, when customer returns it to NEC Corporation for repair and so on. { Put the spacer of 1.0mm thickness or more on a product rear side, because of the protection for contortion. e.g., Washer condition: The washer thickness = 1.0mm (min.) The washer diameter (φ) = 5.0mm (Recommendation) 65PWB31 DATA SHEET EN0560EJ1V0DS00 9 4. OUTLINE DRAWINGS (reference) (Unit: mm)
