Power transformers

The basic function of power transformers is to convert power while matching the operating voltage.

Power transformers are used in power supply systems where voltage matching and electrical insulation are required. Power transformers are designed and manufactured according to the EN 61558.

Typical parameters:

• Primary voltage: ≤ 1,500 V
• Secondary voltage: ≤ 1,500 V
• Insulation class: B, F, or H
• Protection rating: IP00-IP67 (not applicable to leads)
• Designed for installation in a system
• Primary, secondary, double, reinforced insulation (according to EN 61558)

Transformers can be made on the basis of toroidal cores and EI laminates, which makes it possible to adapt the transformer to the assembly conditions. Transformers can be made either open or encapsulated by placing them in a resin-filled housing or by impregnating them.
