Transformateurs 50/60hz : TNC 50/60 Hz Low Profile UL Aproved Transformers 15-42W | PREMO

This series of flat mains transformers has a typical structure in the type of winding used and its layout.

They are made with a pair of “C” half-cores made of steel magnetic plates alloyed with M-4 silicon which are shaped and trimmed after their heat treatment.

Their main feature is their high efficiency, achieved by the type of core used. In addition, they have an increased dielectric strength and very low leakage current, as well as an excellent PERFORMANCE to PRICE ratio.

They are encapsulated in a flame resistant plastic case filled with heat resistant synthetic resin. They are manufactured in 4 standardized power ratings of 15, 25 and 42 VA, with double secondary voltages of 6, 9, 12, 15, 18 and 24 Vac.

Customer-designed models :
By request, we can manufacture customer-designed models with the voltages, power ratings and pin layout different from the standardized ones. The only restriction being that they must be able to fit into the available standard cases and the distribution of pins must be respected. They can also be made in open construction, but their insulation decreases and they lose their resistance to moisture. By request, the TNC standard series is available with 2 primaries at 115 V.
