TOROIDS

Electrical Efficiency, Voltage Regulation, Reduced Size, Weight and Noise. These are just some of the many benefits Q-Tran toroidal transformers provide in low voltage lighting power supply centers. Q-Tran's manufacturing processes include evenly distributed copper wire winding - a technique that reduces air gaps in the Magnetostriction (which is the main source of the “humming” noise associated with stack-laminated transformers).
