Aqua Ultraviolet 40 watt replacement transformer

I used to have four transformers that were connected to one spider shaped configuration that would tear at its plastic encasings (exposed wires) and was a pain in the neck to loosen and take off to clean the quartz sleeves and UV lights. This configuration where each transformer is independently plugged into the power source and separated from an attachment that connected all to one power source makes it simple to disconnect and it is "cleaner" looking cosmetically. If one transformer goes down you can replace it and not worry how the others are affected by its performance since they are all plugged into power source separately. I would highly recommend this product for your pond needs. I bought a large metal fuse box to enclose all of them to protect them from weather elements although they are made weather-proof already, I wanted to consolidate the tidiness of the cords.

Works good!

So far so good. It is what I needed.

A complete unit so it went to work immediately.

I do like this 40W Replacement Transformer as it is easy to replace existing bad-order transformers such as my 120W Aqua UV system which contained a three wire system that went from my lamp holder containing three 40W lamps up to the 120W transformer box. I have replaced the 120W transformer twice, replaced the wiring harness twice in the previous 20 years then decided on going the single 40W transformer route which was about six years ago. I had the 120W Aqua UV system since 1984. I also have a small pond containing a 40W Aqua UV system that I also use this type of a transformer which gave me the idea of using the single 40W replacement transformer.

In less than 24 hours the water returned to perfect clearness. Results Were Amazing --Great Purchase

This is the 3rd. one I had to replace do to water leaking into the the unit. The cord grip seals at the cord but around the outside where the cord enters the transformer it allows water to get in. The transformer is potted with a black tar mixture, but it is poorly done and water gets into the electronics and shorts it out. At about $100.00 each this becomes expensive. Buying just the raw transformer means you have to make some kind of container to put it in. Since this option still costs about $65 you don't save very much. If I could buy the raw transformer for around $20 (which is all it should cost), then it would pay to make a container to put it in. For five years I've been using an old Gamma transformer by Current USA but it seems that it is no longer made.

After 10-12 years it finally gave up the ghost and have to replace Two. As soon as I saw my water turning green I check the bulbs and then the transformers and they finally wore out after many years
