What is BS EN 61951-2:2018?

BS EN 61951-2:2018 is a technical standard that specifies the requirements for safety of extra-low voltage supplied electronic control gear for LED modules. This standard ensures that electronic control gear used in LED lighting systems meets the necessary safety and performance criteria.

Scope of BS EN 61951-2:2018

The scope of BS EN 61951-2:2018 includes electronic control gear operating with an input voltage range from less than or equal to 50 volts AC/DC to 250 volts AC/DC. It covers both independent control gear and those integrated within a luminaries. The standard applies to all control gear intended for use with LED modules used in indoor and outdoor lighting applications.

Safety Requirements

BS EN 61951-2:2018 sets out several safety requirements to ensure the protection of users, as well as the longevity and reliability of the LED lighting system.

One of the essential safety requirements outlined in the standard is electrical insulation. Control gear should provide sufficient insulation to prevent electric shock and other electrical hazards. This standard also dictates the minimum clearance and creepage distances that need to be observed to avoid any potential short circuits.

In addition to electrical safety, BS EN 61951-2:2018 places emphasis on thermal management. It specifies requirements for protecting control gear against overheating, including design considerations for heat dissipation and the protection of components from excessive temperatures.

Performance Criteria

BS EN 61951-2:2018 not only ensures safety but also establishes performance criteria for electronic control gear used in LED lighting systems.

For instance, it covers requirements for electromagnetic compatibility (EMC). LED control gear should be able to operate without causing any interference with other electrical devices and also withstand external electromagnetic disturbances. This standard provides limits for emissions and immunity, reducing the risk of compatibility issues.

Furthermore, BS EN 61951-2:2018 specifies the parameters for output characteristics of control gear, including output voltage, current, power, and efficiency. These requirements ensure that the LED lighting system functions optimally and delivers the desired level of performance.

In conclusion, BS EN 61951-2:2018 is a technical standard that establishes safety and performance requirements for electronic control gear used in LED lighting systems. This standard plays a critical role in ensuring the safety of users, preventing electrical hazards, and guaranteeing the reliability and longevity of LED lighting systems.
