IEC 62384 is an international standard developed by the International Electrotechnical Commission (IEC). The standard is titled "Industrial process control instruments – Methods of checking performance." Its primary objective is to provide guidelines for evaluating the performance of industrial process control instruments, ensuring they meet the necessary requirements for accuracy, reliability, and safety.
: The 2020 update extended the DC supply range from 250 V up to 1,000 V , reflecting the industry shift toward higher-capacity systems.
: Covers controlgear designed to provide a constant voltage or constant current to LED modules.

). The standard outlines rigorous endurance tests where the driver is subjected to elevated temperatures and cyclic switching to simulate years of real-world use. The Difference Between IEC 61347 and IEC 62384
The lighting industry has shifted completely from incandescent bulbs to Light Emitting Diode (LED) technology. This shift requires strict international standards to ensure safety, reliability, and performance.
The standard applies to control gear that operates from a DC supply up to 250V or an AC supply up to 1000V at 50Hz/60Hz. It covers a wide range of drivers, including those with constant voltage output and constant current output. IEC 62384 is an international standard developed by
While the full standard must be purchased directly from the IEC Webstore or authorized distributors like iTeh Standards , the following features and requirements are typically outlined in the document:
: Requirements for mandatory and optional information displayed on the driver. Electrical Characteristics :
The standard mandates clear measurement methods for calculating the total power consumption and overall energy efficiency of the driver. High efficiency minimizes energy loss as waste heat, which directly extends the life of the electronic components. 4. Power Factor (PF) Correction : Covers controlgear designed to provide a constant
Revised test-circuit selection based on module capacitance.
The International Electrotechnical Commission (IEC) standard serves as the definitive global benchmark for the performance of electronic controlgear—commonly known as LED drivers—intended for use with LED modules. As the lighting industry continues its massive shift toward solid-state lighting, this standard ensures that the components powering these systems operate with the efficiency, stability, and reliability required for modern electrical grids. Scope and Purpose
Controlgear must be clearly marked with essential electrical ratings. This includes rated supply voltage, frequency, input current, power factor, and output characteristics (constant current or constant voltage values). 2. Output Voltage and Current Stability
