What is Class II

The IEC standard for LED drivers categorizes them into three classes: Class I, Class II, and Class III. These classes are primarily based on the insulation level and safety performance of the driver. The following are the differences between these three classes:

IEC Class I: Class I drivers have basic insulation and require grounding. They usually come with a metal casing and can protect users from electric shock through grounding. These drivers can be used in both household and industrial applications and typically have higher safety performance.

IEC Class II: Class II drivers, also known as double-insulated drivers, usually do not require grounding. They have double insulation that can protect users from electric shock in case of accidents. These drivers are typically used for low-power applications, such as indoor lighting.

IEC Class III: Class III drivers are typically used for low-voltage lighting systems. They need to be isolated from other power sources to ensure safety. These drivers need to be used with specific types of fixtures and bulbs.

In summary, the selection of IEC driver class depends on the electrical requirements and safety demands of the application.

Most of Antron products meet IEC class I, which require grounding via lead wire or metal case. Some of the product series meet IEC class III, such as constant voltage series driver (12/24/36/48V).
