You might have learned that it is preferable to make use of the Class 2 LED driver in the LED signage and lighting applications so that you can better manage and limit the potential chance of electric shock hazard in installing and operating the devices. However, many people confuse the class 2 (Numeric “2”) with the class II (Roman Numeral “II”) power source. These are both valid standards, controlled by different organizations, however they are intended to provide different protections in numerous methods. This is a brief explanation of each and every designation to assist you distinguishing between the two.
Class 2: Class 2 power supplies are governed by UL (Underwriters Laboratories) 1310 standard. The main target of UL-1310 is to be sure the output from each channel from the power supply cannot exceed 100 Watts (or five times output voltage if is it is less than 20V) in every given circumstances, like the rated working temperature, start-up or de-activate process and also the faulty conditions. UL-1310 is applied to oversee the course 2 LED driver also. If you are a US domestic LED sign or lighting application builder, you need LED driver, not really a Class II power source.
Class II: Class I and sophistication II are generally specified within the EN-60950 (the European standard). The first kind needs a ground connection – usually done by using the 3-prong AC input, established, therefore the extra current generated in the fault condition can be quickly shunt to ground without damaging the property or the operator. The second demands a double insulation on the primary and also the secondary side of the power supply if the ground connection is missing. Class II power supplies are typically found in the telecommunication industry. You can get it resides in numerous electronic products products, including the Digital Video Recorder, network switch and wireless router.
If your signage or lighting application is made up of LED related illumination technology, make sure to employ a Class 2 LED driver to power your system. A LED dirver ul can consist of several output channels nevertheless the maximum output power of each and every channel won’t exceed 100 watts. By limiting the complete maximum output power to the UL predefined level – 100 watts, the course 2 LED driver is able to reduce the possibility of producing excessive out-going current, over-heating the cables and creating an electric shock hazard. Thus, it may support a safer installation and operation experience to your applications.
The continuous processes would be the next stop in the mass processes, which just work at higher volume and minimize variety. These processes could be interpreted since the production activities with longer timescale. Sometimes, the manufacturing lines work endlessly to help make huge quantity of products. These products seem inseparable and they are necessary for a never-ending flow. In certain extreme cases, the continuous processes must work continuously, since the operation has to provide you with the goods without a break. These processes are normally designed to cope with relatively inflexible, capital-intensive technologies with highly predictable flow. To date, these processes gpoktv not applicable for the LED light industry, as the LED tube or LED bulb products are still not too popular inside our everyday routine. The continuous processes are definitely more ideal for the steel making and electricity utilities.
