Uv lamp power supply circuit.
As the replacement of traditional uv transformers uv electronic power supplies are designed for lighting up both uv mercury lamp and metal halide lamp.
0 0047 uf ceramic capacitor c2.
Input output isolation up to 5000vdc.
The emi filtering ic circuit is connected with an input power supply and connected with.
Full encapsulation with thermally conductive potting compound.
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.
However when i assembled the circuit powered with 120vac the bulb only dropped 8 4 vac when carrying 300ma for an effective power of 2 6 watts.
So q2 will need a heatsink if there is a high led current or if the power source voltage is a lot higher than the led string voltage.
Q2 limits the circuit in two ways.
The present utility model relates to a uv lamp power supply circuit.
Output power from 1w to over 200w.
When the time elapses the pin3 becomes zero switching off the triac and the uv lamp.
Absopulse uv lamp inverters offer.
For this circuit we will use 4 5v of power in order to light the uv led.
En55022 class b emi.
The monostable now begins counting and depending on the values of the c1 and r2 the pin3 and the triac remain switched on for a stipulated period of time.
Single or dual outputs.
If you have a dc power supply you can use this and adjust the voltage so that it outputs 4 5v or you can connect 3 aa batteries in series to produce 4 5v.
The positive supply at pin3 activates the triac and the uv lamp.
This simple converter to power uv lamp scheme is a simple converter to power the ultraviolet lamp low voltage.
The circuit comprises an emi filtering ic circuit a rectification filter circuit an igbt voltage reducing circuit a pwm control circuit an igbt full bridge circuit a current voltage open phase monitoring circuit and a load uv tube.
Q2 acts as a variable resistor stepping down the voltage from the power supply to match the need of the led s.
Q2 power dropped volts led current.
The invention provides a uv ultraviolet lamp power supply circuit.
0 1 ufdisc capacitor d1 d2.
The power supply can be applied using the 6 batteries of 1 5v or a power supply with an output current of at least 1 a 8v voltage outout.
12v 24v 28v 48v or custom.
