These high current transformers are based on the current transformer principle, with single or multiple secondary turns. They are suitable for use in test generators for power frequency magnetic fields as specified in EN 61000-4-8:1993. REO also manufacture the variable transformers that are used as voltage regulators.

Features include:
Compact, fully encapsulated, construction
Greatly reduced magnetic stray field
Easy installation (screw fixing)
Enclosed, primary terminals, in accordance with VBG 4
EMC compliant, no additional devices required
Manufactured in accordance with EN 60742 (VDE 0551)
Higher currents using parallel conection
Optional multiple secondary turns
