PULS keeps world’s largest clock shining

PULS has supplied 1,000 high-efficiency DIN-rail power supplies to light 2,000,000 LEDs on the world's largest clock.

The Mecca Royal Hotel Clock Tower in Saudi Arabia boasts several world records, including the tallest hotel in the world, the tallest clock tower in the world, the world's largest clock face, and the world's largest building floor area. Each of the four-faces of the 200 metre-high clock measure 46m, dwarfing London's Big Ben and the Cevahir Mall clock in Istanbul, both of which were once the world's largest. The faces of the clock are illuminated by 2m LED lights and are said to be visible from 25 km. On special occasions, such as New Year, 16 bands of vertical lights shoot 10 km into the sky in a spectacular display. A further 21,000 white and green coloured lights representing the Saudi Flag flash five times a day to call worshippers to prayer. The 1,000 PULS XT 40 DIN-rail power supplies each deliver 1,000w providing the 1,000,000w needed to supply the enormous complex. The high levels of efficiency achieved by PULS - claimed to be up to 95% - means less energy is wasted and therefore less heat is generated, an important factor in a country where ambient temperatures of 40C° are not uncommon. PULS UK's Managing Director Harry Moore said, "PULS power supplies deliver very high efficiency and that was particularly important for the installation in Mecca where we are delivering a full megawatt of power."
