Control transformer / single-phase - 12 - 230 V, 40 - 1 000 VA | TR 21 series
The TR 21 CONTROL Transformers is a control and safety or seclude single-phase transformers. This device employs the principle of mutual induction to proselytize variations of current in a primary circuit into variations of voltage and current in a derivative circuit. The necessary instantaneous power can be equipped for the precise contractors, switch and other gear operations with precise magnanimous flexibility on the double primary voltage and the serial-parallel connection.
