Do You Need a Class 2 or a Class II LED Driver?

By | 24 June 2017

You’ve gotten discovered that it’s preferable to make use of the Class 2 LED driver within the LED signage and lighting purposes to be able to higher handle and restrict the potential threat of electrical shock hazard in putting in and working the gadgets. Nevertheless, many individuals confuse the category 2 (Numeric “2”) with the category II (Roman Numeral “II”) energy provide. They’re each legitimate requirements, managed by totally different organizations, however they’re meant to offer totally different protections in numerous strategies. Here’s a temporary rationalization of every designation that will help you distinguishing between the 2.

Class 2: Class 2 energy provides are ruled by UL (Underwriters Laboratories) 1310 customary. The principle focus of UL-1310 is to make sure the output from every channel of the ability provide can not exceed 100 Watts (or 5 occasions output voltage if is it’s decrease than 20V) in any given circumstances, such because the rated working temperature, start-up or shut down course of and the defective circumstances. UL-1310 is utilized to supervise the Class 2 LED driver as nicely. In case you are a US home LED signal or lighting software builder, you want a Class 2 LED driver, not a Class II energy provide.

Class II: Class I and Class II are each specified within the EN-60950 (the European customary). The previous requires a floor connection – often completed through the use of the Three-prong AC enter, established, so the additional present generated within the fault situation will be shortly shunt to floor with out damaging the property or the operator. The latter requires a double insulation on the first and the secondary aspect of the ability provide if the bottom connection is lacking. Class II energy provides are usually used within the telecommunication business. Yow will discover it resides in lots of client electronics merchandise, such because the Digital Video Recorder, community change and wi-fi router.


In case your signage or lighting software is made up of LED associated illumination know-how, you should definitely make use of a Class 2 LED driver to energy your system. A Class 2 LED driver can include a number of output channels however the most output energy of every channel will not exceed 100 watts. By limiting absolutely the most output energy to the UL predefined degree – 100 watts, the Class 2 LED driver can cut back the prospect of manufacturing extreme out-going present, over-heating the cables and creating an electrical shock hazard. Thus, it may assist a safer set up and operation expertise on your purposes.
