Toroidal - Twin Primary Transformers
115V/230V ac
A high quality range of open style toroidal transformers with flying
leads. Featuring a dual 115V 50/60Hz primary winding for series (230V)
or parallel (115V) connection only. Secondary windings can be
connected in series or parallel or used independently.
Features:
• Very high quality construction.
• High efficiency and smaller size compared to conventional EI transformers.
• Extremely low radiated magnetic field, suitable for sensitive electronics.
• Double insulated primary leadouts.
• Flexible leadouts can be trimmed to any length without the need of removal of enamel.
• Design, manufactured and tested in accordance with EN60742, EN60065 and EN60950.
• 100% electrical and flash tested.
• Supplied with mounting dish, bolt and 2 foam pads.
• Pri/Sec leads 0°
