How to Test a UV Ballast: A Simple Step-by-Step Guide
- Visual Inspection: Start by checking the ballast, UV lamps, and electrical connections. Look for any signs of damage, corrosion, or leaks. Make sure the lamps are clean and free of dust, and confirm that all connections are secure.
- Test Lamp Ignition: Turn on the power and see if the lamps ignite and stay lit. If you notice flickering, a delayed start, or if the lamps don’t light up at all, there may be an issue with the ballast.
- Measure Lamp Voltage: Use a voltmeter to check the voltage of the lamps. For a typical low-pressure UV lamp, the voltage should be around 40-60 VAC once the lamp has warmed up.
- Check Power Supply: Ensure the input voltage to the ballast is within the correct range (for example, 108VAC to 132VAC for a 120V ballast). Also, look out for signs of overheating or charring on electrical connections.
