IEC 62384:2020

Overview

IEC 62384:2020 specifies performance requirements for electronic controlgear (LED drivers) intended to power LED modules. It applies to controlgear supplied from DC or AC supplies (up to 1 000 V, AC at 50 Hz or 60 Hz) and to outputs whose frequency may deviate from the mains. The standard covers controlgear designed to provide constant voltage or constant current to LED modules (IEC 62031) and replaces the 2006 edition with a technical revision published in 2020.

Key topics and requirements

• Scope and classification
  • Applies to DC/AC supplied electronic controlgear up to 1 000 V; edition extends DC capability from earlier 250 V to 1 000 V.
  • Classification by load type (single-value vs multiple-value), output voltage and output current.
• Performance tests (type tests)
  • Type testing requirements (not intended as production-line tests).
  • Tests are carried out with LED modules meeting specified wattage tolerances and with output cable lengths of 20 cm and 200 cm unless declared otherwise.
• Output behaviour
  • Requirements for starting, connection, and stable voltage/current during operation; suitable for devices that deviate from pure voltage/current types.
  • Guidance that compliant controlgear is expected to operate satisfactorily within approximately 92% to 106% of rated supply voltage (per manufacturer specs).
• Power and power quality
  • Total circuit power definition (controlgear + LED module).
  • New 2020 specifications for measuring circuit power factor, including controlgear with settable or non‑constant outputs (e.g., constant light output modes).
• Capacitive loads and test circuits
  • Test-circuit selection is now based on module input capacitance (high vs low), with ~100 nF used as a typical threshold.
  • Special measurement procedures for capacitive load current.
• Other changes
  • Deletion of audio-frequency impedance requirements from the previous edition.
  • Endurance, marking, supply current and operational-abnormal-condition tests defined.

Applications and users

• Who uses it: LED driver and lighting system manufacturers, test laboratories, product certifiers, lighting designers and specifiers, and compliance officers.
• Practical applications: Designing and validating LED controlgear for compatibility with IEC 62031 LED modules; defining type-test protocols; ensuring product performance, interoperability and product claims for dimming/constant light modes; preparing technical documentation and regulatory submissions.
