Why The Same Power Supply With Lamps Of The Same Power Cup (tungsten Filament) Not Lit?
Lamp Cup under cold resistance is very small, light Cup at the rated voltage is applied, moments before the lighting takes a lot of starting current. When the lamp is lit after temperature increases, resistance increases considerably, current down to Cup good current. Due to our products with current limiting protection function, the actual current exceeds the rated output current protection feature will appear. So in the moments before the lamp cup light liquidity current exceeds the rated power of the power supply is lit in front of the Cup the output power of the power supply), the lamp not lit power supply is protected.
