TUM - Single phase transformers 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:
– (x) equals 1/10 of power rating in V
– (y) shows the type of winding – „0″ for dual chamber frame (basic version) and “1” for single chamber frame (reduced shorting voltage)
– (z) shows orientation where “A” signifies vertical version (basic) and ”H” horizontal version.
Rated power: 1600 – 10000VA
Rated voltage PRI: 110 – 1000V 50/60Hz
Rated voltage SEC: 12 – 500V
