Description

This 500VA Toroidal Transformer is an industry standard, with a quality mode of ISO 9000. The industry has quickly recognised the advantages that toroidal provides in terms of size, weight, and lower radiated field.

Toroidal transformers are becoming more popular due to their improved magnetic properties. The toroidal (doughnut) shape has the advantage of minimizing the amount of magnetic flux that escapes outside the core (leakage flux). Thus resulting in less electromagnetic interference (EMI) to nearby circuits or equipment. In today's low-power, high-frequency electronics, EMI is becoming increasingly important.

Toroid transformers can be made with a lower profile than a standard solenoid core transformer, allowing for lower profile equipment with comparable power.

Features

  • Lower electrically induced noise demanded by compact equipment
  • Energy authority certified
  • High efficiency enabling conservative rating whilst maintaining size advantages
