Toroidal Transformers
The Toroidal Advantage
A Toroidal Transformer converts AC supply voltages to one or more AC voltages, for example 230V to 2 x 24V.
Toroidal transformers offer a number of advantages over conventional 50/60Hz laminated transformers:
- Easy to mount
- Low mechanical hum
- Flexible dimensions
- Small size and weight
- Low magnetic strayfield levels
Applications
Toroidal transformers have a wide range of application, including:
- Audio Transformers
- Power Transformers
- Mains Transformers
- Matching Transformers
- Isolation Transformers
Custom Design
Power rating (VA) and voltages according to customer's specification.
- Power rating (VA)
- Number of tappings
- Fixation method
- Wire length (Standard length 300mm)
Power Rating
- Single Phase: 10VA - 15000VA
- Three Phase: Up to 50 KVA
Mounting Options
Standard Mounting Kit
Each transformer is supplied with a mounting kit consisting of a clamping disc and two rubber washers, complete with nut and screw. The toroid is sandwiched between the rubber washers providing an economical and vibration dampened assembly.
Centre-Potted with Insert
An insert is placed in the centre of the core, which is then resined. Mounting is done with a screw and nut.
Data Chart
Power Rating, measured in VA (Volt Amps), is calculated as Voltage * Amps.
For example: 10 VA = 5V * 2A.
