HISTORY:
Those who are old enough will well remember the Ferguson brand name, Australian designed and made transformers. Unfortunately the name is no longer as they were acquired by Telectran International back in 1997.
Highly reliable transformers with very good characteristics, these Ferguson transformers could be found in many Australian made products including the broadcast industry (especially rack mount equipment)
FERGUSON TRANSFORMER
Circa early 1990's (conveniently the original manufacturing date sticker remains on the side!)
Step down
240V AC input (only)
15-0-15V AC output @ 20VA (total power not per winding)
Unique pin arrangement used for all connections and because of this I am supplying the leads with the crimped connectors (colour coded)
Low Profile fully enclosed format
Dimensions: 75mm x 60mm x 40mm hig
Mounting brackets at each end extend the length from 75mm to 110mm with multiple mounting choices
Weight: 600g
Supplied lead lengths:
Secondary (Orange/Yellow) 80mm (each) minimum
Primary (Blue/Brown) 200mm (each) minimum
COSMETIC CONDITION:
Excellent and although the transformer is used you wouldn't know it
TESTING:
Removed from fully functioning (but extremely obsolete) audio broadcast equipment.
Retested after removal:
OC secondary voltage 16.63V each winding (two separate windings - not a tap) This means that the rated RMS output voltage is what you can expect under full design load, roughly 650mA RMS each winding, this is plenty of current for most low level audio or electronic equipment. Especially suitable for Op amp circuits where a dual rail power supply is required, typically 15-0-15V DC
