Block recently announced that they will obsolete a number (around 500) of standard products.
These are products from different product groups:
· Both single- and three-phase transformers
· Both isolation transformers and auto-transformers
· Different power ranges (from a few VA to tens of kVA)
Transformers that are 1:1 identical to EREA standard products do not exist, but for various applications it is possible that an EREA standard product can be used as a substitute.
Because EREA also offers custom-made products, we can offer a customised alternative for many of these products. We can build the transformer completely identical or, because it is custom-made, we can omit certain features that are not used in your application.
