COB series product specifications are as follows: in line with ANSI MacAdam ellipse 4 step CCT specifications; general light efficiency of 90 to 110 lumens / watt or more; color rendering CRI (Ra) greater than 80, light output angle up to 160 degrees, module forward drive voltage Can be controlled in a very small range, is the best choice for a variety of LED lamps or bulb lighting.
At the same time, in order to develop and design LED lamps with simplified and low-cost power supply, Ricoh Optoelectronics has also successfully developed 110V/220V high-voltage driving COB light source for C70/C90, which is currently limited by space and cost. Lighting products have the best application choice.
According to the research, the new COB series has a very good light color effect in indoor lighting. For example, bulbs, projection lamps, downlights, etc., have no dark area problems, and can be provided at 25°, 35°, 55° angles.
Air conditioner Contactor is mainly applicable to a line of AC 50Hz or 60Hz,rated working voltage up to 600V and rated working current up to 60A,used to close or switch off the line.The Coil Insulation is Class B(130℃),can be operated with 85% of nominal coil voltage or 110% maximum safe operate.
Air conditionar Contactors are definite purpose:AC Contactor are designed for use in refrigeration,and electric heating systems.Power connections can be made with either screw terminals with quick connects or lug terminals with quick connects.
