Isolation and Power Transformer - ETR 3P60KVA

ETR Galvanic Isolation Transformers provide isolation between network installations and sensitive electronic loads. Insulated aluminum or copper windings are wound on a high efficiency sheet core. ETR transformers are vacuum-impregnated varnished and high-temperature dried to ensure quiet and moisture-proof operation. It is safe and long lasting.

ETR Isolation Transformers

Provide isolation between network installations and sensitive electronic loads.
Insulated aluminum or copper windings are wound on a high efficiency sheet core. ETR transformers are vacuum-impregnated varnished and high-temperature dried to ensure quiet and moisture-proof operation. It is safe and long lasting. It is designed and produced in different power, different voltage and different vector features according to customer demands.
It is produced in the power range of 1kva-600kva as single phase and three phases for industrial applications.





Voltage Changing and Supply Transformers

It is used for safe operation and voltage changing in machines or electronic devices. They are designed as double winding isolated type or single winding auto type.
Specially designed cabinet for indoor and outdoor applications. Outdoor cabinet with high protection class up to IP65 according to customer needs. Project-specific protection and display options.

Soft-Start Feature (optional)

A Soft-Start unit can be added to limit the high currents generated during initial energizing. Soft-Start circuit reduces the inrush current of the transformer by 1/3. It provides a solution for ship and yacht applications where instant high currents adversely affect electronic devices. Soft Start feature is available for cabinet option.

Outdoor Type Cabinet and Protection Options

Special cabinet option with high protection class up to IP54 for special applications. Voltmeter, Ammeter and signal lamp options are offered together with the special cabinet designed according to the project needs. Fuse and over temperature protection can be added for Input and Output side.
