Royal Clock Tower in Mecca
When night falls in Mecca, the green dials of the world’s largest clock tower are still clearly visible at a distance of over 10 miles. This is achieved with two million LEDs – and around 1000 power supplies.
PULS has been entrusted with providing these power supplies. This project placed particular demands on the inrush current. Selected PULS products can cope with the very high inrush currents that occur when 1000 power supplies are switched on simultaneously. The requirement for low heat generation was achieved due to the high efficiency of up to 95.5% and compact size. Additionally, as the tower is 601 meters high, the power supplies must have high immunity to a possible lightning strike in order to ensure uninterrupted service.
PULS Dimension XT series, 48V / 20A fulfil all of these challenging requirements and deliver the one million watts of power that are required to illuminate the LEDs in the Royal Clock Tower in Mecca. Read more
