Electrostatically shielded transformers KLMPH

Encapsulated mobile single-phase electrostatically shielded transformers are suitable for equipment which need to be protected from mains power transients and interference. The transformers have been manufactured with toroidal transformers.

Due to their compact size, low noise level and beautiful and durable enclosure, they are suitable for a wide range of applications. The enclosure has an integrated carrying handle, which makes the transformer easy to move around. The transformers are equipped with electrostatic shields and secondary filters.

Electrostatically shielded transformers are used for suppression of mains power interference and as isolation transformers. The transformers’ structure allows for a good suppression of common-mode and differential mode interference voltage.

A fault current guard (e.g. Trafox Superintend® VRE-16) can be connected to the transformer for monitoring of the connections of the secondary winding and devices connected to it. In this case, the secondary winding must be grounded. If the transformer’s secondary winding should be isolated from the ground, its insulation level can be monitored with an insulation monitoring system. Additional information is available on the Trafox Superintend® IMD website.

The transformers can also be customized with a speedy delivery to correspond to the customer’s requests and standards.
