Three Phase Metal Cased Transformers
Our transformers in this range are suitably protected by a sheet metal case. They are normally wall mountable up to 2500VA and floor standing above this rating although portable styles can also be supplied. Many requirements are for isolation and/or conversion of three phase machines, or creation of a neutral where none is available. Our standard metal cases are IP23, but we can supply up to IP66 if required. Usually with little or no addition to the supply lead-time.
All our isolation transformers incorporate an electrostatic screen between the primary and secondary windings and are built in compliance with the latest European standards. Other worldwide standards, e.g. UL, CSA can also be met.
In addition, isolation from the main supply may not be required, and in this instance an auto wound transformer may be considered to economise on size and cost.
These transformers are also available without enclosures for panel mounting - see Open Frame Control Transformers Three Phase.
