Toroid open wound dual 115V primary

High quality open style toroidal transformers with dual 115Vac 50/60Hz primary windings and twin secondary windings which may be connected in series or parallel or used independently.

Features & Benefits

• Small size and low weight compared with traditional stacked lamination types;• Extremely low level of radiated magnetic field;• Very low induced noise (hum);• Very low iron loss;• Double insulated primary leads

Note

Mounting hardware is not supplied, available seperately

Warning

Under no circumstances should both ends of the fixing bolt simultaneously contact the metal chassis or framework as this would create a potentially dangerous 'shorted-turn'.
