many advantages of custom designed toroidal transformers are
now available to you in small quantities with little investment
When our standard transformers are not suitable or when exact
output data cannot easily be established, you now have a less
expensive alternative to a full custom design. Toroid Corporation
offers kits with factory made primaries, available in five power
ratings and come with complete instructions. All kits are made
for 60 Hz operation.
Calculate Volts x Amps (RMS) for each winding.
The SUM of these VA-ratings must be smaller than the rated
VA for the kit to be chosen.
Rated DC power replaces the VA rating if the transformer
is used to supply rectifiers with capacitor filters as loads.
Calculate PDC = (DCVolts + 2) x DCAmps for each
bridge rectifier supplied by the transformer. The SUM of
the PDCs for all rectifiers must be smaller than the Rated
DC Power for the transformer. If any rectifier uses two
diodes and a center tapped secondary instead of a regular
bridge conversion, its PDC is: 1.4 x (DCVolt + 1) x
kit does not include magnet wire for the secondary windings.

Options The price for the kit (please see chart) does not
include engineering assistance to calculate wire size and
length. Should you like us to do this work for you, we would
be happy to help you for a fixed fee of $175.00 per design.
Required magnet wire would then be shipped with the transformer
kit from the factory at no extra charge.
