Rated coil voltage
However, the notation of the coil voltage on the product case as well as on the packing will be marked as
@@VDC.
Note 2. When ordering tape packing, add "-SP" to the model number.
Be sure since "-SP" is not part of the relay model number, it is not marked on the relay case.

白光LED光衰原因之荧光粉性能的衰退 到目前，白光 LED、尤其是小功率白光 LED 的发光性能快速衰退已越来越为人们所认识。其实，盲目地夸大宣传，只能将 LED 行业引向歧途，不正视白光 LED 存在的问题，只能延缓白光 LED 应用的发展。只有正视问题、研究问题、尽早解决问题，白光 LED 才能健康、快速发展。 白光 LED 当前面临的一个主要问题就寿命问题。由于白光 LED 的价格尚很...[详细]
