Figures given above are maximums for any given VA Maximum ambient temperature 40°C. Overall temperature rating class A (105°C). Secondary voltage tolerance ±1% at nominal input and full resistive load. No mounting screw supplied.
All leads 150 mm long, stripped and tinned for last 6 mm.
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.
