Constant Current LED Driver Power Supply Transformer Premium Quality
To comply with all UK building regulations any electrical work should be carried out by a UK certified electrician. All electricity should be switched off prior to any electrical work being carried out. Due to the reactive power often encountered in lamps, the transformers are always about 30-40% more selected. Usually, the transformer has 20% Power Loss. Please never exceed the maximum connected load. Due to the reactive power often encountered in lamps, the transformers are always about 30-40% more selected
