Avel Y236803 500VA 35V+35V Toroidal Transformer
Avel Y236803 500VA 35V+35V Toroidal Transformer is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Avel Y236803 500VA 35V+35V Toroidal Power TransformerI purchased the Avel Y236803 500VA 35V+35V Toroidal Transformer for use in a 500 watt, 50 volt DC linear power supply for a Class-D amplifier board (the 2x300W TAS5630 Class-D Amplifier Board, Part # 320-309). Along with the transformer, the power supply also uses a 200 volt, 25 amp bridge rectifier and two 68,000 uF at 63 volt aluminum capacitors. The transformer is very heavy duty and built like a tank. The primary leads are double insulated. All mounting components (two pads, a bolt, washer, nut and top plate) are included. The toroidal design of the transformer core makes it magnetically self-shielding, so no hum or noise is introduced into sensitive audio circuits. Also, unlike conventional laminated core transformers, a toroid has no loose plates to buzz at 60 Hz. The transformer is completely silent running. I loaded up the transformer to full power with power resistors. I found the regulation to be dead on to the spec. The output voltage holds very nicely under a heavy load. I will never again use conventional laminated core power transformers. The toroidal design works so much better, runs cooler, runs completely silent and has better load regulation. Absolutely nothing negative to say about it. Attached is the diagram of the power supply I used this transformer with. Note that the DC positive and negative for the amplifier board is NOT tied to frame ground. This allows the amp to "float" and eliminates ground loops and induced hum. If you decide to build a supply like this, be SURE to observe polarity (especially the capacitors). Connect them backwards and they CAN EXPLODE! Be careful!

Do you have this kind of transformer?

500VA Torroidial Power TransformerPrimary: 115V/230VSecondary: 24V/20.8A (*SINGLE* output, not dual)
Asked by: robles
The Avel toroidal transformers that we have feature two secondary outputs. You could wire the outputs of the transformer that I've linked below in parallel, for a single 25V, 20A output.
