Bender ES710 Medical Isolation Transformer

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 the primary and secondary winding the lead out of which is connected to an insulated
terminal for connection to the equipotential bonding.
The fixing angles are isolated from the transformer core in order to guarantee an isolated
installation to comply with the requirements of DIN VDE 0100-710 (VDE 0100-710): 2002-11,
para. 710.512.1.6.2).

The transformers are available for horizontal and vertical installation. Protection against
corrosion is guaranteed by a complete resin impregnation. The transformers are designed for
use in dry locations. Transformers of the SK2 series are completely encapsulated and fulfil the
requirements of protection class II.
