Artificial intelligence and intelligent lighting technology continue to develop, application scenarios continue to expand, and market demand also increases. The design and application of controllers have become a trend in the industrial industry. UL also has different standards for controllers, such as UL 8750, UL 60730, UL 1472, UL 773A. What are the differences and differences between these standards?
Controller UL certification-UL 8750 certification
UL 8750 updated the standard in 2021-01-05. Any controller that controls LED, no matter where it is installed, as long as it controls LED lights, can apply for UL 8750 certification. The certification mark for parts or the whole machine needs to be given the corresponding certification mark according to the product design.
However, if it is a typical dimmer switch mounted on the wall, UL 8750 is still not acceptable, because of the requirements for the panel, UL 8750 standards do not involve part of UL 514D.
Controller UL Certification-UL 773A
UL 773A is mainly used to evaluate optically controlled switches, human body induction switches, infrared switches and electronic switches used in buildings or outdoor lamps. CCN is WJCT/7, which gives the certification mark of the whole machine. The upper cover of the shell material is at least 5V and the lower cover is above V-2 grade.
Controller UL Certification-UL 60730
UL 60730 is mainly used to evaluate controllers for household or similar purposes. CCN is ATNZ/7, which is suitable for various control products. The plastic shell requires 5VA. The electronic controller for UL 60730 may not be equipped with Air-gap switch (mechanical switch), and the output load size of the electronic controller is not controlled.
Controller UL Certification-UL 1472
UL 1472 standard is applicable to controllers permanently fixed on the wall, or dimmers, with WIFI or without WIFI,CCN is EOYX/7. Such products explicitly require products to have Air-Gap Switch, and plastic shells require V-2 flame retardant grade. In addition, UL 1472 requires at least 300W or more for loads, at least two types of loads, LED types and incandescent lamps.
Controller UL certification how to choose the right standard
1. Different controllers have different usage scenarios, and the corresponding priority standards will be different;
2, look at the buyer's market positioning and choice.
Attention point
if the product uses Relay, the load type of Relay must match the load type used in product certification. If it does not match, the durability test of the corresponding load shall be added for additional evaluation.
extended
regarding control, you can also add an intelligent module to a traditional socket to make a smart socket. There are two evaluation methods:
1, with UL 60730 UL 498 to evaluate, UL 60730 to evaluate the controller part, UL 498 part is used to evaluate the socket.
2. UL 498B UL 498: intelligent socket. UL 498B corresponds to the controller part and is the controller of UL 498B. The standard is clearly applicable to sockets permanently fixed on the wall. CCN is RTXI/7.
