25V + 25V 300VA Toroidal Transformer

240VAC PRIMARY TOROIDAL TRANSFORMERS

High quality open style toroidal transformers with a single 230V a.c. 50/60Hz primary winding. Twin secondary windings may be connected in series or parallel or used independently.

FEATURES:

Small size and low weight compared with traditional stacked lamination types to meet modern slimline requirements.
Extremely low level of radiated magnetic field
Very low induced noise (hum) to meet requirementsdemanded of compact equipment
Very low iron loss
Higher efficiency enabling conservative ratings whilst maintaining size advantages.
Double insulated primary leads
100% electrical and flash tested
High quality manufacturing and testing in accordance to EN61558, EN60742, EN60950, EN60065, VDE0551,VDE0550 and BS415
pproved to Australian standard AS3108
Energy authority app. CS348/W.
Supplied with mounting kit - Simple quick single bolt mounting
Each transformer is supplied with 2 x Neoprene washers, 1 x steel dished washer, 1 x Mounting bolt and Nut.

Important Installation Note
Each transformer is supplied with a dished washer and protection pads for single hole fixing. Ensure that the padsare fitted above and below the transformer winding and that the dished washer is on top of the upper pad. Do not overtighten the fixing bolt (not supplied) as this could damage the winding.
Under no circumstances should both ends of the fixing bolt contact a metal chassis or frame as this would create a'shorted turn' causing irreparable damage.
