You have learned that it is preferable to utilize 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, lots of people confuse the class 2 (Numeric “2”) with the class II (Roman Numeral “II”) power supply. They are both valid standards, controlled by different organizations, however are designed to provide different protections in numerous methods. This is a brief explanation of each designation to assist you distinguishing between the two.
Class 2: Class 2 power supplies are governed by UL (Underwriters Laboratories) 1310 standard. The target of UL-1310 is to ensure the output from each channel of the power source cannot exceed 100 Watts (or five times output voltage if could it be is less than 20V) in almost any given circumstances, such as the rated working temperature, start-up or turn off process and the faulty conditions. UL-1310 is applied to oversee the course 2 LED driver as well. In case you are 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 Class II are generally specified in the EN-60950 (the European standard). The previous requires a ground connection – usually done by utilizing the 3-prong AC input, established, and so the extra current generated inside the fault condition could be quickly shunt to ground with no damage to the home or even the operator. The latter calls for a double insulation on the primary and also the secondary side from the power source in the event the ground connection is missing. Class II power supplies are generally found in the telecommunication industry. You will find it resides in numerous consumer electronics products, like the Digital Video Recorder, network switch and wireless router.
If your signage or lighting application consists of LED related illumination technology, make sure to use a Class 2 LED driver to power your system. A LED dirver ul can contain several output channels however the maximum output power of each channel won’t exceed 100 watts. By limiting the complete maximum output capacity to the UL predefined level – 100 watts, the category 2 LED driver is effective in reducing the possibility of producing excessive out-going current, over-heating the cables and creating an electric powered shock hazard. Thus, it may support a safer installation and operation experience to your applications.
The continuous processes are definitely the next stop of the mass processes, which work at higher volume and lower variety. These processes can be interpreted as the production activities with longer timescale. In some instances, the manufacturing lines work endlessly to make huge quantity of products. These products seem inseparable and are required in an endless flow. In some extreme cases, the continuous processes must work continuously, because the operation needs 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. Up to now, these processes gpoktv not applicable towards the LED light industry, as the LED tube or LED bulb items are still not too popular inside our everyday routine. The continuous processes are more ideal for the steel making and electricity utilities.
