Description:Tas uv curing offer highes quality ballast and capacitor(uv curing lamps supply) ballast transformers are used to initiate and control the arc in mercury and metal additive curing lamps. Ballast provide an instantaneous high voltage to strike the elements within a mercury vapor lamp, creating a plasma that once initiated, is susstained by the ballast. Total wattages upto 50 kilowatts can be designed. Our constant wattage ballast consists of a transformer, capacitors and ignitor. The advantage of a constant wattage ballast is that it allows for wide variations in input voltage to affect output wattage by only a few percent. These range can be customize to meet your applications requirements. Typical designs have an output varication of only +/-3% with an input voltage -constant wattage is accomplished by a resonant tank circuit in which lamp winding is in a controlled magnetic saturation with AC capacitors, such that voltage swings on the input side have a very small impact on lamp current. An interesting feturer is that these current limiting capacitors can be switched in and of the circuit to provide various lamp power levels. -ballasts are avaliable in 50,60 or combination of 50/50 hz. Typically, input power factor is better than ninety(90%) percent at nominal input voltage. Ballasts are constucted using silicon grain oriented steel, ul rated copper wire, ul class h insulation system and impregnated with a unique epoxy vanish for maximum thermal transfer.
