BS EN 62735-2-2013 is a technical standard that sets requirements for the safety and performance of information technology equipment. It specifically focuses on reducing hazards caused by external power supply units used with IT equipment. The standard was developed by the British Standards Institution (BSI) and provides guidelines for manufacturers, suppliers, and users to ensure the safety and reliability of IT equipment.
Scope and Purpose
The scope of BS EN 62735-2-2013 covers external power supply units used with IT equipment to power them or charge their batteries. These power supplies can be either direct-plug-in types or AC-DC adapters. The purpose of the standard is to define technical requirements, test methods, and procedures to ensure that these power supply units are safe, reliable, and conform to specific environmental considerations.
The standard primarily addresses potential risks associated with electrical, thermal, mechanical, and environmental aspects of external power supply units. This includes protection against electric shock, fire hazards, energy efficiency, electromagnetic compatibility (EMC), as well as durability and resistance to moisture and dust ingress.
Key Requirements and Tests
Under BS EN 62735-2-2013, power supply units must comply with specific requirements to ensure their safety and performance. These requirements include input voltage limits, output load conditions, maximum temperature rise, and insulation properties. Manufacturers need to meet these requirements and conduct various tests to verify their compliance before placing these products on the market.
Some of the key tests performed on power supply units include dielectric strength testing, measurement of earth continuity, determination of leakage current levels, and evaluation of energy efficiency. These tests help evaluate the ability of power supply units to withstand electrical stress, ensure proper grounding, prevent electric shock, and maximize energy efficiency.
Conclusion
BS EN 62735-2-2013 plays a crucial role in ensuring the safety and reliability of external power supply units used with IT equipment. By complying with this technical standard, manufacturers can deliver products that meet stringent quality requirements and provide users with assurance that their equipment is safe to use. Furthermore, adherence to this standard helps in reducing potential hazards, improving energy efficiency, and minimizing environmental impact. It serves as a valuable guideline for the industry as a whole and contributes to the overall advancement of information technology equipment safety.
