Description
Single-phase transformers with standard UI shape lamination with composite core are intended for horizontal mounting. They 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 ambi-ent 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.
JHT – horizontally mounted on Z-shape brackets with transformer terminal blocks
JHP – horizontally mounted on Z-shape brackets with terminal blocks
JHR – horizontally mounted on Z-shape brackets with feed-through terminal blocks
