Taiyo Yuden Co., Ltd. (Chairman and General Manager: Mian Guan Yingzhi, Headquarters Address: Taito District, Tokyo) produces ultra-high-end products - cylindrical lithium-ion capacitors with high energy density and long life. Recently, they have raised the upper temperature limit of their operating temperature range to 85 °C, successfully overcoming the technical problems of the product in high temperature environment.
The above products can be used for the centralized meter reading system used by the smart grid or the backup power source for the smart meter body, and the SSD storage server is equal to the backup when the instantaneous voltage drop occurs. With this capacitor configuration optimization, the upper temperature range of the operating temperature range can be increased from 70 ° C at the maximum operating voltage of 3.8 V to 85 ° C at 3.5 V (the upper limit temperature of the conventional products at the above two voltages can only be maintained at 60 ° C).
This high-temperature-resistant product has been in operation since September 2012, and has achieved a monthly output of 100,000 units in the subsidiary TAIYO YUDEN ENERGY DEVICE Co., Ltd. (Chairman and General Manager: Sakae Shoji, company address: Ueda City, Nagano Prefecture) Production. The reference price is 500 yen for LIC1235R3R8406, 1,000 yen for LIC1840R3R8107, and 2,000 yen for LIC2540R3R8207.
The smart grid enables a wide range of power control through communication functions. In order to realize and ensure a variety of power supply modes such as anti-blackout and power supply adjustment, the centralized meter reading system and smart meter used have been equipped with wireless communication function and real-time locking function. In this context, the battery used in the standby power supply of the traditional electric meter has been unable to meet the increasingly demanding use of the battery, and the market calls for a battery that has a longer life and can supply more current in wireless communication. For such special applications, cylindrical lithium ion capacitors with high energy density, long life, and high withstand voltage characteristics are beginning to emerge.
However, since the centralized meter reading system and the smart meter are installed outdoors, the components they carry must be able to adapt to work in a high temperature environment. Conventional cylindrical lithium-ion capacitors use a temperature range up to 60 ° C. The market needs a revolutionary new product that works at higher temperatures.
The solar lure is aimed at this demand, and successfully realized the structural optimization of its cylindrical lithium ion capacitor products, further improving the reliability of the product, while maintaining the product size and capacitance, the internal resistance is unchanged. Next, the upper temperature range of the operating temperature range is raised to 70 ° C. Not only that, but it can operate normally even at a high temperature of 85 ° C at a maximum operating voltage of 3.5V.
In the future, Taiyo Yuden Co., Ltd. will continue to accurately grasp the market demand for large-capacity, develop lithium-ion capacitors, and accelerate the development of research and development in the field of energy equipment.
The above products were exhibited at the Taiyo Yuden booth at the 14th High-Tech Achievements Fair Electronics Show (November 16-21, Shenzhen Convention and Exhibition Center Hall 2).
â– Use
It can be used for backing up backup power supplies such as meter reading systems, smart meters, and SSD storage servers.
The product line of this commercial cylindrical lithium ion capacitor is as follows
Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
