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. 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.Specifications Safety Standard: AS/NZS 61558 – 2 – 6 Certified Primary voltage: 240V AC 50Hz Secondary voltage: 25V (parallel), 50V (series) Secondary current: 20A (parallel), 10A (series) Regulation: Better than 10% Maximum temperature rise: 75°C Maximum ambient Temperature: 25°C Dielectric strength: 4000V for 1 Minute Insulation class: Class B (130oC) Tolerance: ± 2% Thermal Protector: Thermal cut – out 17AM033A5 130°C 9A 250V Winding Wire: Enamelled Copper Pri.
