Is this power adapter made for the CT-500-UV?
Yes. This replacement is intended for the CT-500-UV Ultraviolet Countertop Water Purifier and its compatible 10-watt UV lamp configuration.
What is the model number of the ballast?
The supplied unit is labeled RW3-425-18A. The replacement product number is QR-1377.
Is this the UV lamp?
No. This is the electronic ballast/power adapter that powers the UV lamp. The replacement UV bulb is a separate component.
What voltage does the adapter use?
The supplied ballast label specifies 120V AC, 50/60Hz input.
What UV lamp does the CT-500-UV use?
The CT-500-UV uses a 10-watt UV lamp rated at 425 mA. The system's lamp is rated for approximately 9,000 hours, or about one year of continuous operation.
Can I use this adapter with another UV purifier?
Match the ballast model, lamp wattage, current, connector, and electrical requirements before using it with another UV system.
How do I know if my CT-500-UV transformer needs replacement?
A UV lamp that will not operate can be caused by the lamp, ballast, connection, or another electrical issue. Check the lamp and connections before assuming the transformer has failed.
Does the adapter include a new UV bulb?
No. This listing is for the replacement transformer/electronic ballast only. A CT-500-UV replacement UV bulb is sold separately.
Do I need an electrician to install it?
The adapter uses plug-in connections, but UV equipment contains electrical components. Disconnect power before servicing and use a qualified technician if you are unsure about the installation.
