Series vs. Parallel discussion & help:
Our EP (printed-circuit) and EU (low profile printed-circuit) transformer
models offer both "series" and "parallel" output options.
While the output VA (volt Amps = output volts x output current) remains
the same for the individual part, the series and parallel output voltages
and currents will change. For example, our model EP06-1-010 has a series
output of 10VAC@0.60A and a parallel output of 5VAC@1.20A. In both cases,
output volts times the output current equals the base 6VA rating.
Whether one chooses series or parallel option is only a decision as to
how the transformers will be hooked up.
In a series hook-up, the transformer's secondary (output)
windings have the like or same polarity terminals connected.
With parallel, the transformer's secondary (output) windings
have the alternate polarity terminals connected.
When asked by our interactive database, find the required output voltage in either
the series or parallel sections. If the output voltage is shown
in both sections and there is a question as to which is needed, click
the voltage in both sections to see both series and parallel options
for the selected output voltage. After submitting, a list of available
catalog units and specifications will be generated for review.
