TUM - Jednofázové transformátory IP00

Opened build of general purpose transformers for building into installations and industrial or power engineering devices. The transformers are made with Class I insulation and protection grade IP00, maximum ambient temperature 40°C, thermal class of insulation B (130°C). Manufactured in compliance with EN 61558. Variations coding: TUM (x)(y)/(z) e.g. TUM 2501/H, where:

1. (x) equals  1/10 of power rating in VA,
2. (y) shows the type of winding – „0″ for dual chamber frame (basic version) and “1” for single chamber frame (reduced shorting voltage),
3. (z) shows orientation where “A” signifies vertical version (basic) and ”H” horizontal version.

Rated power: 1,6 – 20kVA
Rated voltage PRI: 110 – 1000V 50/60Hz
Rated voltage SEC:12 – 500V
Short circuit voltage: ≥15% (TUM xxx0); ≤5% (TUM xxx1, TUM xxx2)
