If you already have transformer designs, we will be pleased to quote for their
manufacture. Just send us your drawings!
If you would like us to design transformers to meet your requirements, please send
us the following information. If you do not have all the information available, please
just give what you can.
1.
Specify the application. (For example, Switched Mode Power Supply (SMPS)
in an instrument). Please give as much information as you can.
2.
Indicate by a schematic or describe how the transformer is driven and used.
(For example, push-pull FET drive in a SMPS). Please give as much information as
you can.
3.
Draw a schematic of all windings with turns ratios and widest acceptable
tolerance of turns ratios. Indicate polarity of windings where it is important. For
windings with one or more taps between the ends, please make clear what turns
ratios are required for each section of the winding!
4.
Specify what voltage isolation requirements there are between all windings.
5.
Draw or describe the voltage waveform which will be applied to the primary
winding. If the waveform is variable, please specify the extremes.
6.
Specify maximum working currents to be drawn from all secondary windings.
7.
If occasional overload conditions have to be met, please specify these
seperately.
8.
Specify the maximum dimensions of the space you have available for the
transformer.
9.
Specify if you require surface mounting or through-hole mounting.
10.
If you have a preference for a particular hardware design (for example ETD,
RM or toroidal), please state it.
11.
Specify your estimated requirements of quantities and delivery dates both for
short term and long term. This is important because it may influence what hardware
is specified for the design.
12.
If you have a target or maximum price level, please state it.
