You've got learned that it's preferable to implement the Class two LED driver from the LED signage and lighting applications to be able to better regulate and limit the possible hazard of electrical shock hazard in setting up and working the equipment. On the other hand, Lots of individuals confuse the class 2 (Numeric "two") with The category II (Roman Numeral "II") electricity source. They may be both valid criteria, controlled by diverse corporations, However they are meant to deliver various protections in several solutions. Here is a brief explanation of every designation to help you distinguishing among the two.

Class 2: Class 2 electricity provides are ruled by UL (Underwriters Laboratories) 1310 conventional. The main target of UL-1310 is usually to make sure the output from Just about every channel of the facility offer simply cannot exceed a hundred Watts (or 5 periods output voltage if is it can be lower than 20V) in almost any specified instances, including the rated Performing temperature, start out-up or shut down course of action along with the faulty circumstances. UL-1310 is placed on oversee The category 2 LED driver as well. If you are a US domestic LED indication or lighting software builder, You'll need a Class two LED driver, not a Class II ability offer.

Class II: Course I and Class II are both equally specified in the EN-60950 (the ecu common). The former needs a ground link - generally finished by using the three-prong AC input, recognized, so the extra latest generated during the fault issue can be speedily shunt to floor with no harming the home or maybe the operator. The latter calls for a double insulation on the principal as well as secondary side of the ability source if the bottom connection is missing. Class II ability supplies are typically Utilized in the telecommunication field. You'll find it resides in lots of purchaser electronics goods, such as the Digital Video clip Recorder, network change and wi-fi router.

Summary:

If the signage or lights software is built up of LED related illumination engineering, you'll want to hire a category two LED driver to electric power your process. A category 2 LED driver can consist of numerous output channels but the maximum output energy of each channel will not exceed a hundred watts. By restricting the absolute highest output electrical power for the UL predefined level - a hundred watts, The category 2 LED driver can lessen the probability of manufacturing excessive out-likely latest, about-heating the cables led driver manufacturer and generating an electric shock hazard. Thus, it may possibly guidance a safer installation and Procedure knowledge to your applications.
