Description
Double-chamber single-phase transformers with standard EI shape lamination with composite core are pro-duced in accordance with ČSN EN 61 558 in any voltage transfer combination between 1 V and 1 000 V, fre-quency 50/60 Hz, protection IP00, 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 shielding, higher insulation class, higher ambient temperature, primary or secondary winding protection, or the addition of thermal fuses.
ZU – horizontally mounted on Z shape brackets with soldering lugs
VO – vertically mounted on brackets with soldering lugs
PJ – vertically mounted on brackets with soldering lugs and fuse holder
