Y23 Range transformers are constructed to high standards, and are certified to or in compliance with most worldwide safety agency standards (see below) . Our unique double-insulated primary leads eliminate an assembly step required by many safety standards. If your requirement falls outside our Standard Range, we would be pleased to quote on a custom design (see page 11 for custom transformer specification guidelines and request form) .  \nGeneral Specifications  \nPrimaries: 115V + 115V.
