Title: Isolation Transformers and Power losses according to wattage
Post by: Kiriakos GR on March 03, 2025, 11:38:23 PM
This information comes from a German company and a manufacturer, of Isolation Transformers.
According to Isolation Transformers sizing in Watts there is also an portion of power losses.

INPUT / OUTPUT in Ampere ( 230V 50Hz)
1.2    / 1 A
2.35  / 2 A
4.8A  / 4 A
6.9A  / 6 A
11.0  / 10 A 

The learning is that the lower in watts model of transformer, at 1A this has 20% of conversion losses.
While the larger 10A variant this has 10% of conversion losses.

Naturally when selecting an Isolation Transformer, losses comes last as a decision factor.
The primary decision factor, this is the delivery of enough supply of AC current for your application.

Either way, if you plan operating an Isolation Transformer 24/24?
The ones considered as larger models, these will do the job by wasting less energy.  ;)
