The Antek 500VA heavy duty toroidal power transformers have 4 individual outputs of 15Vac at 8.3A each. It operates at continuous duty for stepper or servo motors. They are specially designed to work on all standard 115V or 230V at 50Hz or 60Hz. These transformers have heavier gauge wires than the normal requirement to avoid the copper lost during the full power output.  The dielectric test is more than 3500V in between primary and secondary coils. In most of the cases, this transformer can be output 20% more power from its rating at 60Hz power source without any problem. This transformer comes with 2 rubber pads and all mounting hardware.
