Note: Under no circumstances should both ends of any fixing bolt be allowed to come simultaneously in contact

with metal chassis or framework so that an electrical path is formed through the bolt in the centre of the transformer

via the external framework. This would constitute a shorted turn and would cause irreparable damage.

TA DATA issue 2. 17/12/02

technical changes reserved

TA Range Toroidal Transformers.

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

Very high quality construction.

High efficiency and smaller size compared to conventional EI transformers.

Extremely low radiated magnetic field, suitable for sensitive electronics.

Flexible lead outs can be trimmed to any length without the need of enamel removal.

Designed, tested and manufactured in accordance with EN60742, EN60065 and EN60950.

UL recognised to UL1411 under file E115159

100% electrical and flash tested.

Maximum ambient temperature 40 degrees C.

Overall temperature rating Class A (105 degrees C.)

Secondary voltage tolerance +/- 1% at nominal input and full resistive load

All leads 150mm long, stripped and tinned for last 6.0mm

No mounting screw supplied
