25 + 25 500VA Toroidal Transformer

by: Powertran
SKU: M5725C
Toroidal transformers are becoming increasingly popular due to their improved magnetic properties and also that they can be made to a lower profile than a standard solenoid core transformer, allowing for equipment of similar power to be of a lower profile such as rack mounted devices.

Overview

Toroidal transformers are becoming increasingly popular due to their improved magnetic properties. The advantage of the toroidal (donut) shape is that due to its symmetry the amount of magnetic flux that escapes outside the core (leakage flux) is minimised, therefore it radiates less electromagnetic interference (EMI) to nearby circuits or equipment. EMI is of increasing importance in modern low power, high frequency electronics.

Toroid transformers can be made to a lower profile than a standard solenoid core transformer, allowing for equipment of similar power to be of a lower profile.

The entire range has been tested and approved to the Australian standard AS/NZS 61558.2.6. This standard is equivalent to the European standard EN61558.2.6 making the transformers suitable for the European market (where 240V is used).

Manufacturers please note, we recommend that a sample is obtained to confirm suitability.

Features:

  • Lower electrically induced noise demanded by compact equipment.
  • High efficiency enabling conservative rating whilst maintaining size advantages.
  • The toroidal transformer is accepted as the industry standard, replacing the laminated type as toroidal transformers offer advantages in size, weight, and lower radiated field.
