Isolation Transformers

Foster's Isolation Transformers build on the rugged reliability of our Machine Tool Control transformers adding a Faraday shield and Class 180 (H) Insulation System.

The Faraday shield reduces the capacitive coupling between the primary and secondary windings attenuating common mode noise and enhances safety by providing a grounded connection between the inputs and outputs.

Transformers are shown with screw terminals, but can be ordered with flexible lead wires or a variety of terminal blocks.

Don't see what you need? Call, fax, or email. Foster has over 16,000 designs in its database and we develop new designs for our customers everyday.

Foster Transformer Company is the perfect choice for custom and standard isolation transformers designed to comply with UL 506, UL 60950-1, UL 60601-1, EN 61558-1 and EN 60601-1.
