Description
Encapsulated double-chamber single-phase transformers with standard EI shape lamination are produced in accordance with ČSN EN 61 558 in any voltage transfer combination between 1 V and 1 000 V, frequency 50/60 Hz, protection IP00, terminals IP20, insulation class B and a maximum ambient temperature of 40 °C. Their sizes and rated outputs are shown in the table. Optional changes to the design include protective shield-ing, higher insulation class, higher ambient temperature, primary or secondary winding protection, or the addition of thermal fuses.
VV – encapsulated transformer with cables
VS – encapsulated transformer with input cable and output terminal
SS – encapsulated transformer with input and output terminals
HA – encapsulated transformer type VV,VS or SS for halogen lights in class III
