Uv Lamp Power Supply Circuit

Input output isolation up to 5000vdc.

Uv lamp power supply circuit.

The present utility model relates to a uv lamp power supply circuit. 0 0047 uf ceramic capacitor c2. 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. Q2 power dropped volts led current.

Output power from 1w to over 200w. The positive supply at pin3 activates the triac and the uv lamp. The circuit comprises a 380v ac alternate current input rectifier filter unit a step down main circuit unit a full bridge variable frequency output unit a feedback unit a main control driving unit and a uv lamp wherein the 380v ac input rectifier filter unit is connected with an input power supply and is sequentially. Pushing the bulb to 10 5 vac would exceed this current limitation and likely shorten the life of the bulb.

The invention provides a uv ultraviolet lamp power supply circuit. Immunity to shock vibration humidity moisture dust and insectss. En55022 class b emi. As the replacement of traditional uv transformers uv electronic power supplies are designed for lighting up both uv mercury lamp and metal halide lamp.

Full encapsulation with thermally conductive potting compound. 12v 24v 28v 48v or custom. The emi filtering ic circuit is connected with an input power supply and connected with. 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.

Q2 limits the circuit in two ways. 0 1 ufdisc capacitor d1 d2. Single or dual outputs. 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.

This simple converter to power uv lamp scheme is a simple converter to power the ultraviolet lamp low voltage. With the application of inverse square wave technology uv electronic power supply can regulate uv output steplessly as well as save electric energy 40. Absopulse uv lamp inverters offer. 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.

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. For this circuit we will use 4 5v of power in order to light the uv led. 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.
