Low Profile Transformers Low Boy
ª
Series
Explanation of Low Boy Interconnections.
Because of the toroidal effect, two identical coils are connected in series or
parallel, but one of the coils must be connected in reverse in order to get correct polarity and voltage.
The Low-Boy power transformer is designed to surpass competitive market offerings in cost, size and versatility to the
designer. Applicable to low clearance, stacked printed circuit board and solid state power designs, the Low-Boy will allow
closer board stack spacing at lower power levels (down to 200 mA at 10 volts). Semi-toroidal construction reduces radiated
magnetic fields and results in balanced windings. Non-concentric winding provides isolation by design, eliminating the need
for an electrostatic shield. Allow
