Isolating transformer

Safe voltage with ES710 isolating transformer

The single-phase isolating transformers are used to set up medical IT systems. The reinforced insulation ensures operation in accordance with the requirements of DIN EN 61558-1 (VDE 0570-1) and DIN EN 61558-2-15 (VDE 0570-2-15).

An IT network can be created with an isolating transformer can be created.


In IT systems, all active parts are Parts are either insulated from earth or connected to earth via a high-impedance connected to earth. The high-resistance impedance can be provided for measurement reasons reasons, but with the proviso that electrical safety is not jeopardized. The bodies of the electrical system are earthed either individually or together.


What is the difference to TN and TT systems?


In TN systems, the neutral point of the supplying transformers is is earthed with a low resistance and the bodies of the electrical system are Connected to the system's protective earth conductor. In TT systems the neutral point is also earthed with a low resistance, but the bodies of the electrical System are earthed independently of the system earthing.


Mains isolating transformers are used to separate energy networks from each other. They are often used in workshops and laboratories Laboratories, for example, in order to carry out repair work and experiments safely and for the operation of all-current devices in order to minimize the risk of electric shock when working on mains Devices or equipment to minimize the risk of electric shock.


Mode of action:


One generates an output voltage that is not connected to earth, the potential difference to earth can assume any any value up to the insulation strength, without a current flowing through the body current can flow through the body to earth when a single conductor on the secondary side is touched Earth can flow through the body.


Our project managers will be happy to help you select the right transformer and provide you with a specific quotation. Scheduling and logistical processing are carried out in consultation with you, which is why these isolating transformers are not offered online in the store.
