What is BS EN 61347-2-7 – Lamp controlgear about?
BS EN 61347-2-7 is an international standard that discusses the safety requirements for lamp controlgear. Lamp control gear is an electrical device intended for household electrical installation that limits the current of the lamp or supplies constant current or constant voltage to power LED lighting.
BS EN 61347-2-7 specifies safety requirements for battery supplied electronic controlgear for maintained and non-maintained emergency lighting purposes. BS EN 61347-2-7 includes specific requirements for electronic controlgear and control units for self-contained luminaires for emergency lighting as specified by IEC 60598-2-22.
BS EN 61347-2-7 is intended for controlgear for fluorescent lamps, but it is also applicable to other lamp types e.g., incandescent, high-pressure discharge lamps and LEDs. BS EN 61347-2-7 covers the emergency mode operation of a controlgear. For controlgear with a combination of normal and emergency lighting operation, the normal lighting operation aspects are covered by the appropriate part 2 of IEC 61347.
BS EN 61347-2-7 includes operational requirements for electronic controlgear, which, in the case of d.c. supplied electronic controlgear, are regarded as performance requirements. This is because non-operational emergency lighting equipment presents a safety hazard.
Note: BS EN 61347-2-7 does not apply to d.c. supplied electronic controlgear for emergency lighting, which is intended for connection to a centralized emergency power supply system. A centralized emergency power system could be a central battery system.
Who is BS EN 61347-2-7 – Lamp controlgear for?
BS EN 61347-2-7 on lamp controlgear applies to:
- Manufacturer of lamp control gear
- Quality testing personnel
- Electrical engineer
Why should you use BS EN 61347-2-7 – Lamp controlgear?
Lamp controlgear is one or more components between the supply and one or more lamps that may serve to transform the supply voltage, limit the current of the lamp(s) to the required value, provide starting voltage and preheating current, prevent cold starting, correct power factor, or reduce radio interference.
BS EN 61347-2-7 specifies the extent to which such a clause is applicable and the order in which the tests are to be performed; they also include additional requirements, as necessary. All parts which make up IEC 61347-2 are self-contained and, therefore, do not include references to each other.
With BS EN 61347-2-7 you can be ensured that the lamp control gear products consistently meet and exceed quality assurance targets.
