[] Mitsumi show demonstration of LED lighting power supply module and display 60W level high power products

Neturen in the "2008 Mitsumi show (MITSUMI SHOW 2008)" on display at the LED lighting power supply module, and the lighting and dimming demonstration. The power module display includes support for 100/120V AC input "PSU-501/502/503BS" 3 products and product support 220/240V AC input. Equipped with power factor improvement circuit, can reduce the generation of high harmonics. The life of the power module can be guaranteed over LED lighting fixtures. The photoelectric conversion efficiency of the power supply module depends on the dimming condition, which is about 70 ~ 80%. PSU-501/502/503BS will begin production in April 08. Three the output parameters of the products are different, the output voltage and output current of the PSU-501BS are DC 44V, maximum 120mA, PSU-502BS is 12V, 300mA; PSU-503BS is 12V, 350mA. The utility model is mainly used for the spotlight and the illumination of the lamp in the shop. Demonstration, according to the real-time changes in the position of the knob. "The brightness of LED and the current input are nonlinear. In order to make the brightness change linearly, the amount of current is changed with the external potentiometer. In addition, considering the convenience of use, the shape of the power supply module is improved to be slender. When the construction personnel in the installation of the LED lighting to the ceiling, through the ceiling to set up the hole to set up the LED lighting module plug the power module to the ceiling. In order to improve operability, the shape is designed to be slender ("the company"). The output voltage and output current of the power module are 95V and 700mA respectively. LED lighting lamps for indoor lighting. LED input power of more than 60W, up to 10 times more than the above 3 products. In the future, LED plans to Mitsumi electric lighting power supply module as standard products, expand the product line. Reference to the power module will be displayed as the largest power products to the future product line
