Touch and Remote Control Intelligent Safety Dimmer - TLC
... Note: Certain transformers may not behave according to their power rating when used with a dimmer. An overload will result in the safety features of this dimmer turning down the brightness. If so change your transformers to ones which do not appear as an overload, remove one (or some) transformer(s) ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
