In UL certification, CLASS P and CLASS 2 are classifications of specific types of electrical equipment, mainly used to describe their safety features and application scope. FCC is the abbreviation of the Federal Communications Commission of the United States, which is responsible for regulating and certifying the radio frequency interference of electronic equipment. Here is a detailed explanation:
CLASS P
Definition: CLASS P is a classification of LED drivers that meets the specific requirements of the UL 8750 standard.
Features:
Thermal protection: It has a fixed thermal protection limit to prevent the driver from overheating.
Reliability: Strict design and testing requirements ensure stability and reliability under various environmental conditions.
Application: Mainly used for LED lighting drivers to ensure their safety and performance in high temperature environments.
CLASS 2
Definition: CLASS 2 is a power supply category defined according to the UL 1310 standard, which limits the output voltage and current to ensure safety.
Features:
Output limit: The maximum output voltage is usually not more than 60V DC, and the maximum output power is not more than 100W.
Safety: Since the output energy is limited, it will not cause danger to the human body even in the worst case.
Application: Widely used in low-power applications such as LED lamps, small electronic devices, etc. to ensure high safety.
FCC
Definition: FCC is the Federal Communications Commission of the United States, which is responsible for regulating fields such as radio, television, cable TV and satellite communications.
Features:
Radio frequency interference: The equipment must comply with radio frequency interference (RFI) and electromagnetic compatibility (EMC) standards to prevent harmful interference to communication networks and other devices.
Certification: The equipment must be tested by an FCC-approved laboratory, and submit test reports and related documents to obtain certification.
Application: Applicable to all radio frequency devices sold and used in the United States, such as computers, mobile phones, wireless network equipment, etc.
Overview
CLASS P and CLASS 2: These classifications mainly involve safety standards for LED drivers and power supply equipment. CLASS P focuses on thermal protection and reliability in high temperature environments, while CLASS 2 ensures the safety of the equipment by limiting the output voltage and power.
FCC: Responsible for managing radio frequency interference and electromagnetic compatibility of electronic equipment to ensure that the equipment does not cause harmful interference to communication networks and other equipment.
For manufacturers and consumers, understanding these classification and certification standards helps to choose safe and reliable equipment and ensure its compliance and stable performance in the market.
