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.
