320w Electric Ballasts For Two Pcs 90w-155w UVC Lamps Electronic Ballast
The role of ballasts
There are mainly two aspects:
1. Generate high pressure, the ignition lamp tube breaks the rare gas in the lamp,
2. After the lamp starts to glow, it plays the role of ballast (current limiting), so that the lamp can work normally and stably.
Gas discharge lamps have high starting voltage and low discharge sustaining voltage. When the lamp is started through high voltage, the voltage drops and the current increases. If there is no restriction, the lamp current will continue to increase until the lamp burns out, so it is necessary to discharge A ballast that matches the type and specification of the lamp is connected in series in the lighting circuit of the lamp to provide a high starting voltage to start the lamp, and limit the lamp current to stabilize it within the specified range
For some lamps, the ballast also has the effect of heating (preheating) the electrodes at both ends of the lamp.

Product Presentation
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.
