Overview
IEC 61204-6:2000 is an international standard established by the International Electrotechnical Commission (IEC) that specifies requirements for low-voltage power supplies with direct current (d.c.) output. This part of the IEC 61204 series focuses on power supplies designed for general-purpose applications, especially those intended for mass production. The standard applies to power supply units converting alternating current (a.c.) to d.c. or d.c. to d.c., with input voltages up to 600 V and output voltages below 200 V d.c., covering power outputs typically up to 2.5 kW, extendable up to 30 kW with appropriate testing methods.
The key objective of IEC 61204-6 is to define performance requirements and quality assurance procedures to ensure reliability, safety, and conformity of low-voltage power supplies in general use, thereby supporting manufacturers and users in achieving consistent product quality through standardized testing and classification.
Key Topics
-
Scope and Application
Applies to general-purpose low-voltage power supplies with d.c. output, covering products from modules for printed circuits to power supplies up to tens of kilowatts. It addresses power supplies converting a.c. or d.c. inputs to regulated low-voltage d.c. outputs.
-
Classification and Testing
The standard classifies power supplies into four types based on power rating and form factor:
- Type A: Modules for printed circuits
- Type B: Power supplies up to 250 W excluding Type A modules
- Type C: Power supplies greater than 250 W and up to 1 kW
- Type D: Power supplies greater than 1 kW
It mandates procedures for initial product approval, batch testing, and periodic quality verification to ensure ongoing compliance with performance specifications.
-
Performance and Quality Control
Requirements cover electrical characteristics, stability, safety considerations (with reference to related safety standards), and quality control testing protocols. This includes tests during initial production approval and ongoing assessments for batch conformity and periodic production quality checks.
-
Standardization and International Cooperation
IEC 61204-6 forms part of the IEC 61204 series, which includes terminology, electromagnetic compatibility (EMC), safety requirements, and test methods for low-voltage d.c. power supplies. The standard supports international unification by aligning national technical requirements and encouraging transparent application of consistent testing criteria.
Applications
IEC 61204-6:2000 is critical for manufacturers, designers, and quality assurance professionals in the electronics and electrical industries who produce or use low-voltage power supplies. Typical applications include:
- Industrial and commercial equipment requiring stable d.c. power inputs
- Consumer electronics with low-voltage d.c. power components
- Embedded systems and modules utilizing printed circuit power supply modules
- Power electronics equipment used in automation, control systems, and telecommunications
By adhering to this standard, organizations can:
- Ensure product reliability and performance consistency in series production
- Facilitate compliance with internationally accepted criteria for power supplies
- Minimize risks related to functional failure, quality deviations, or safety hazards
- Streamline product testing and certification processes across global markets
