You may have learned that it is preferable to use the Class 2 LED driver within the LED signage and lighting applications so that you can better manage and limit the potential probability of electric shock hazard in installing and operating the devices. However, many individuals 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 are designed to provide different protections in different methods. Listed here is a brief explanation of each designation that will help 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 guarantee the output from each channel in the power supply cannot exceed 100 Watts (or 5 times output voltage if is it is lower than 20V) in every given circumstances, including the rated working temperature, start-up or turn off process and the faulty conditions. UL-1310 is applied to oversee the category 2 LED driver too. Should you be a US domestic LED sign or lighting application builder, you require LED power supply, not really a Class II power source.
Class II: Class I and sophistication II are both specified within the EN-60950 (the European standard). The previous demands a ground connection – usually done by using the 3-prong AC input, established, therefore the extra current generated inside the fault condition may be quickly shunt to ground without damaging the property or perhaps the operator. The latter calls for a double insulation on the primary and the secondary side in the power supply in the event the ground connection is missing. Class II power supplies are typically utilized in the telecommunication industry. You will find it resides in numerous electronic products products, including the Digital Video Recorder, network switch and wireless router.
If your signage or lighting application consists of LED related illumination technology, be sure to use a Class 2 LED driver to power your system. A LED dirver ul can contain several output channels nevertheless the maximum output power of each channel won’t exceed 100 watts. By limiting the complete maximum output capability to the UL predefined level – 100 watts, the course 2 LED driver is effective in reducing 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 for your applications.
The continuous processes would be the next stop in the mass processes, which just work at higher volume and reduce variety. These processes may be interpreted as the production activities with longer timescale. Sometimes, the manufacturing lines work endlessly to make huge volume of products. The products seem inseparable and therefore are required in a continuous flow. In certain extreme cases, the continuous processes are required to work continuously, since the operation needs to provide you with the goods without having a break. These processes are typically designed to deal with relatively inflexible, capital-intensive technologies with highly predictable flow. Up to now, these processes gpoktv not applicable towards the LED light industry, as the LED tube or LED bulb products are still not so popular in our everyday living. The continuous processes are more appropriate for the steel making and electricity utilities.
