Isolating transformer ES710 Single-phase isolating transformers for the design of medical IT systems Also available as energy-efficient Green Line (GL) edition

Isolating transformer ES710 Single-phase isolating transformers for the design of medical IT systems Application and description The transformers of the ES710 series have reinforced insulation and comply with the requirements of IEC 61558-1/DIN EN 61558-1 (VDE 0570-1) and IEC 61558-2-15/DIN EN 61558-2-15 (VDE 0570-2-15). In addition, the transformers comply with the requirements of IEC 60364-7-710/DIN VDE 0100-710 (VDE 0100-710) for IT systems in medical locations. The windings are galvanically isolated. In order to minimize electrical interferences, an electrostatic screen is installed between...

When performing installation work in the environment of the transformer, it has to be ensured that the insulation coordination of the transformer is not influenced in a negative way. For example, no ferromagnetic and conductive metal swarf may fall down close to the transformer. This can interfere with the function and the dielectric properties, especially after being turned on. The environment of the transformer must be kept free from such particles during the entire operating time and controls must be carried out at regular intervals.

Green Line transformer (energy efficient version) – High degree of energy saving over the life time (16 years AfA) (German AfA table for depreciation of wear and tear) Purchase price + energy consumption EUR This general illustration is based on calculations of the transformer’s energy consumption while energy costs remained constant at 13.4 ct/kWh (source: first energy) for 16 years. The wide variety of bandwidths result from the different transformer capacities. Afa = Deprecation of wear and tear = Standard version = GL version (Green Line) = A higher purchase price of approx. 15-20% = ROI...
