Ballast design a 26w electronic ballast circuit without pfc is designed around the irs2526ds mini8 ballast control ic.
Electronic ballast circuit for uv lamp.
An electronic ballast will convert power frequency to a very high frequency to initialize the gas discharge process in fluorescent lamps by controlling voltage across the lamp and current through the lamp.

An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit.
An electronic ballast or electrical ballast is a device which controls the starting voltage and the operating currents of lighting devices.
Ballasts vary greatly in complexity.
A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube which would otherwise rise to a destructive level due to the negative differential resistance of the tube s voltage current characteristic.
It does this through the principle of electrical gas discharge.
They may be as simple as a resistor inductor or capacitor wired in series wi.
Less light for the same input power and different vstrike and von voltages.
A complete range of surelite high efficiency electronic ballasts are available to provide superior and reliable performance of ster l ray germicidal ultraviolet lamps.
Wiring diagrams for workhorse and fep models located on pages 19 21.
They definitely contain a bit of mercury vapor the seller is ignorant and or lying.
Ul listed ballast lamp combinations locate your lamp model in the left column sorted by the type and size find the corresponding fulham ballast and wire diagram in the right columns according to the number of lamps and start type.
If the ballast has heater outputs you re probably scuppered.
The vco pin sets the frequency of the half bridge gate driver outputs ho and lo pins.
Atlantic ultraviolet s surelite electronic ballasts for uv lamps have been extensively tested with ster l ray germicidal uv lamps and are strongly recommended to achieve the best performance and longest lamp life.
Company confidential gas discharge lamp basics 3 low pressure fluorescent lamp current flows through plasma between electrodes must be ac or mercury migrates to one end plasma emits mostly uv radiation uv excites coating to fluoresce and produce visible light heated electrodes improve lamp life and lower strike voltage argon and mercury vapor.
There is no circuitry inside the bulbs it s the type of ballast.
The circuit includes figure 5 the complete control for the half bridge resonant output stage and the lamp.
Electronic ballasts for ultraviolet lamps.
Owing to the expertise of our team of experienced professionals we are able to introduce an exclusive range of uv lamp se 70a 5yg electronic ballast.
A simple low cost electronic lamp ballast cannot optimize the overall efficiency along the lifetime of the tube but the circuit must be designed to guarantee the operation of the lamp even under the worst case end of life conditions.
