You have learned that it is preferable to use the Class 2 LED driver in the LED signage and lighting applications in order to better manage and limit the potential risk 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. They are both valid standards, controlled by different organizations, however they are intended to provide different protections in numerous 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 of the power supply cannot exceed 100 Watts (or five times output voltage if is it is lower than 20V) in every given circumstances, including the rated working temperature, start-up or de-activate process as well as the faulty conditions. UL-1310 is applied to oversee the Class 2 LED driver also. 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 both are specified in the EN-60950 (the European standard). The first kind needs a ground connection – usually done by utilizing the 3-prong AC input, established, so the extra current generated inside the fault condition could be quickly shunt to ground without damaging the property or the operator. The second calls for a double insulation on the primary as well as 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 can get it resides in many consumer electronics products, such as the Digital Video Recorder, network switch and wireless router.
If your signage or lighting application is comprised of LED related illumination technology, be sure to use a Class 2 LED driver to power your system. A LEDA driver 12v can contain several output channels nevertheless the maximum output power of each and every channel won’t exceed 100 watts. By limiting the absolute maximum output capacity to the UL predefined level – 100 watts, the course 2 LED driver is effective in reducing the risk of producing excessive out-going current, over-heating the cables and creating an electric powered shock hazard. Thus, it could support a safer installation and operation experience for the applications.
The continuous processes are definitely the next stop of the mass processes, which work on higher volume and reduce variety. These processes can be interpreted as the production activities with longer timescale. Sometimes, the manufacturing lines work endlessly to create huge quantity of products. These products seem inseparable and are necessary for an endless flow. In certain extreme cases, the continuous processes are required to work continuously, as the operation has to provide you with the goods without a break. These processes are usually designed to deal with relatively inflexible, capital-intensive technologies with highly predictable flow. To date, these processes gpoktv not applicable towards the LED light industry, because the LED tube or LED bulb items are still not so popular in our everyday living. The continuous processes are more suitable for the steel making and electricity utilities.
