 TAS UV Curing offers
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 sustained by the ballast. Total wattages up
to 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 customized
to meet your applications requirements. Typical designs have an output
variation of only+/-3% with an input voltage
Contant
wattage is accomplished by a resonant tank circuit in which the 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
feature is that these current limiting capacitors can be switched in
and of the circuit to provide various lamp power levels.
Ballasts
are availble in 50,60 or combination of 50/60 hertz. Typically, input
power factor is better than ninety (90%) percent at nominal input voltage.
Ballasts are constructed using silicon grain oriented steel, UL rated
copper wire, UL Class "H" insulation system and impregnated
with a unique epoxy varnish for maximum thermal transfer
