Uv Lamp Input Voltage

Capacitive reactance ballasts overcome this problem by the use of capacitors connected in series with the lamps.

Uv lamp input voltage.

Input current to ballast 10 000 0 92 0 90 220 44 47 amps. Medium pressure uv lamps do not have a filament. These capacitors maintain a constant voltage output to the lamp even when the input voltage varies and is the more efficient of the two. There are 3 three main components in a power supply for uv curing lamp magnetic choke electronic ballast and constant wattage transformer.

The pt is placed in parallel with the lamp. They utilize a high voltage charge to ionize a mercury gas mixture in the lamp creating a plasma that emits uv light. How to measure lamp voltage. A resistor is needed so that we can bias and limit the current so that the correct amount flows to the led.

Ballast input voltage 220vac. This system requires a high voltage amperage power supply typically a magnetic ballast transformer with a high voltage capacitor bank. Since lamp voltages can exceed the safe measuring range of most meters a potential transformer pt is required. A typical 100 1 ratio is normally used.

To power a uv led all we need is the right voltage and current.
