Our System dims to about 5% and does not turn off.

Let us know!

That issue is absolutely Not related to the transformer.

If the dimmer does not go to Zero or does not switch the power off, then anything powered by the dimmer will still be energized.

Electronics (DIMMERS) are usually the source of most of these types of issues. You can Bypass the dimmer or you can also try a different dimmer to test the system.


Did you take a voltage AND Amperage Measurement?


I have always found this to be a dimmer issue; could be related to minimum load; you can prove this out by trying with a 20W, then step up to 35W, 50W, and 75W lamp; one at a time to see if the problem you are having goes away.  If it does, then you know placing a greater load is required.  Most electronic devices require a minimum load to operate properly


If that is the case and the dimmer states that a minimum load is required to operate, then using a load resistor is probably required.

A 50W, 1000 ohm resistor could solve the issue; depending what load is already present?.

This would be wired in AFTER the dimmer and before the transformer/Load - Across the line (onto the hot on one side and the neutral on the other)

(120v*120v)/1000 ohms = 14.4 Watts at 120 VAC

This means it Adds 14.4 Watts to the load on the dimmer/circuit, so it MUST BE HEATSINKED.

When we provide these for customers, we utilize a Surface Mounted METAL Wiring Box with an internal heatsink.
