Balanced Transformers

The Balanced Power Transformers are designed with a center-tapped secondary winding which consists of two identical, mirrored secondary windings in series and an electrostatic shield. When the center tap is grounded, these two identical windings short circuit the equal amplitude but opposite phased noise current and greatly attenuate (low to medium frequency) common mode noise. The ground noise amplitude goes to zero, which eliminates audio to be free of noise interference. In addition, our balanced transformers are designed with very low flux density to further reduce the mechanical noise. This series of transformers are perfect for audio recording, production studios and high-end home entertainment systems.

UL and CSA Agency Files
UL and CSA have issued the following reference (file) numbers for our construction approvals received for all our standard designs and over 500 custom designs.


Smaller transformers are supplied with one metal washer and two rubber pads, for power ratings up to 800VA. Larger transformers are typically supplied with an epoxy potted center with a hole for mounting.  Other mounting options are available:

Enclosures
The above transformers can be ordered mounted inside a NEMA enclosure with or without fuse, receptacle and line cord with plug.

Vertical Mounting
When vertical mounting of the transformer is required we recommend using our Omega or L- brackets. Learn more at our Mounting and Hardware section.

Detailed datasheets are available for
all listed part numbers.
Caution - If you choose to apply your own mounting solution, remember that it is important that our transformer be mounted in such a way that the mounting screw and the metal chassis will not form a closed loop through the center and thereby create a shorted turn on the transformer.
