206w Electric Ballasts For Two Pcs 42w-75w UVC Lamps Ballasts
The basic composition of the ultraviolet sterilizer is the ultraviolet germicidal lamp tube and the power distribution system. The main part of the power distribution system is the ballast. Therefore, it can be said that the ultraviolet sterilizer is composed of ultraviolet germicidal lamps and ballasts.
According to the disinfection specification for ultraviolet sterilizers promulgated by the Ministry of Health, when the power supply voltage is 220V, the ultraviolet radiation intensity of 253.7nm wavelength must not be lower than 70μW/cm2, and the level of ultraviolet intensity directly affects the effect of disinfection. The UV intensity depends on the matching of UV germicidal lamps and ballasts. At present, most of the ballasts of ultraviolet sterilizers use electronic ballasts.
Electronic ballasts have the advantages of energy saving and consumption reduction, rapid low-voltage start-up, and high power factor. They have become a replacement product for ultraviolet germicidal lamps to start, and are basically used in ultraviolet germicidal lamps. The main reasons are low cost and low failure rate. Good quality and high power factor. The ultraviolet sterilizer manufacturer Shijiazhuang Lingzhuo Environmental Protection Equipment Co., Ltd. can find through experiments that when the same ultraviolet germicidal lamp is replaced with an electronic ballast, the power consumption can be reduced by more than 25%, while the radiation intensity can be increased by more than 12%. Tube life is greatly extended. Especially for some ultraviolet germicidal lamps that use inductive ballasts and the radiation intensity does not meet the disinfection requirements, as long as the radiation intensity is above 60μW/cm2, when switching to electronic ballasts, the requirements can be basically met.
Electronic ballasts do not have high requirements on the power supply voltage of UV sterilizers. As long as the power supply voltage is higher than 180V, the minimum radiation intensity of 70μW/cm2 can be achieved. Ultraviolet sterilizers replace traditional magnetic ballasts with electronic ballasts. Although the one-time investment is relatively high, in the long run, its potential economic benefits are very considerable. Of course, the premise of realizing the above functions is that the ultraviolet germicidal lamp and the ballast must be matched.
When the electronic ballast of the ultraviolet sterilizer is more powerful than the ultraviolet germicidal lamp, the ultraviolet germicidal lamp is easy to ignite, but the ultraviolet germicidal lamp is easy to age and shorten its life. Because the inductive reactance of the electronic ballast is too small and the passing current is too large, the voltage at both ends of the ultraviolet germicidal lamp is too high, and the life of the filament is reduced. When the power of the electronic ballast is too small than the power of the ultraviolet germicidal lamp, it is difficult or impossible to ignite. Because the inductive reactance of the ballast is too large and the passing current is too small, the voltage across the ultraviolet germicidal lamp is too low, and the filament cannot be ignited. Therefore, the power of the electronic ballast is higher than that of the ultraviolet germicidal lamp, and the lamp tube bears too much current, and the life of the ultraviolet germicidal lamp is reduced.
This is our company's description of the importance of matching the UV sterilizer germicidal lamp and ballast.
Ballasts can be complicated. Nobody replaces ballasts regularly. Inevitably, ballasts are needed when you go to change out the UV bulb at your machine's recommended intervals when you realize that the new bulb is not lighting up or is flickering. Instead of an easy UV bulb switch, your maintenance just became a potentially complicated electronic ballast search and installation.
Finding the right ballast is the first hurdle but not the only one. Even after you take receipt of the ballast, you have to figure
out how to wire them. Depending on the bulb type and the number of bulbs in your system, the wiring can change completely. It is not incredibly complicated, but more troublesome than it is worth for the majority of UV air or water purification system operators.
we want to take the guesswork out of ballast replacement. With this ballast, you are guaranteed to receive the right
ballast with the right wiring diagram. Any questions, and we'll be here every step along the way to help you out.
