Smart design of the enclosure

The clever design of the box with easily removable parts, allows easy installation and connection of cables.

Output voltage accuracy

It is achieved by tapping, without the need to disconnect the power cord.

High resistance to corrosion environment

All materials are selected according to strict criteria, including their high resistance to any corrosive environment, while in addition, a special two-layer Interpon Redox Plus paint system is applied, which further strengthens the high corrosion resistance of the metal shell.

High resistance to shock conditions

Our naval transformers are made with special anti-vibration bases and fully meet all the special requirements for naval warships in extreme shock conditions.

Full functionality on large slopes of the ship


In addition, all the other advantages of the MAR-TC transformers apply.
