WHY A TOROID? - Smaller size and weight to meet modern slimline requirements - Low electrically induced noise demanded by compact equipment - High efficiency enabling conservative rating whilst maintaining size advantages - Simple, quick, single bolt mounting The Toroidal transformers is now accepted as the standard in the industry, quality mode to ISO 9000 overtaking the obsolete laminated type. Industry has been quick to recognise the advantage toroidals offer in size, weight, and lower radiated field. Current ratins on toroidal transformers. Can be used in 2 ways:- A) Both secondary windings in series - double volts B) Both secondary windings in parallel - higher amps. The windings need to be connected in pahse. 20VA LOW PROFILE The height is only 32mm, which means they will fit into a 44mm rack case. - Size 0/D 75, I/D 27 x 32mm Secondary Series Secondary Parallel Cat.
