You have got discovered that it's preferable to use The category 2 LED driver in the LED signage and lights programs as a way to better regulate and limit the potential possibility of electric shock hazard in setting up and working the equipment. Even so, A lot of people confuse The category 2 (Numeric "2") with The category II (Roman Numeral "II") power provide. They are equally legitimate specifications, managed by different companies, Nevertheless they are supposed to offer unique protections in different strategies. Here is a short rationalization of each and every designation that can assist you distinguishing concerning The 2.

Course two: Course two power supplies are governed by UL (Underwriters Laboratories) 1310 regular. The principle aim of UL-1310 is to make sure the output from Every channel of the power supply can't exceed 100 Watts (or 5 times output voltage if is it is lower than 20V) in almost any specified instances, including the rated Performing temperature, start out-up or shut down course of action plus 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 floor link - usually performed by using the three-prong AC enter, proven, so the additional recent created while in the fault situation is often rapidly shunt to floor without detrimental the assets or even the operator. The latter requires a double insulation on the primary along with the secondary facet of the power provide if the bottom relationship is lacking. Class II electrical power provides are generally used in the telecommunication market. Yow will discover it resides in many buyer electronics solutions, including the Electronic Video Recorder, network switch and wireless router.

Conclusion:

In case your signage or lighting application is created up of LED relevant illumination technological know-how, make sure to use a Class 2 LED driver to led driver solution power your method. A Class two LED driver can encompass various output channels but the utmost output electricity of every channel is not going to exceed one hundred watts. By limiting absolutely the utmost output electric power to your UL predefined degree - 100 watts, The category 2 LED driver can reduce the opportunity of manufacturing abnormal out-going current, over-heating the cables and building An electrical shock hazard. Hence, it could support a safer set up and operation working experience in your programs.
