Tier 1 Transformers Stock Availability

We have stopped manufacturing Wilson e1 transformers in light of the new Tier 2 EU Ecodesign regulation. However, we still have Tier 1 transformers in stock that are available for sale and they are good for budget-sensitive projects.

Following the EU Ecodesign regulation, our stock of Wilson e1 transformers has already been placed in the market and can be sold and installed even after 1st July. Please note that we have a limited stock availability so these transformers will be sold on a first come first served basis. If you have projects in the pipeline, we might have to offer you Tier 2 alternatives once the stock is depleted.
