20 Watt Converter Operational Details
There are several operational details of the 20W TWR series to be
aware of when applying these converters.
20 Watts maximum power
The total maximum power for all outputs is 20 Watts. This is the
sum of each separate output. Any one output may achieve its
maximum power as long as the sum of all outputs for the whole
converter does not exceed 20 Watts.
For example, using model TWR-5/3000-15/500-D12A, if the maxi-
mum power is drawn from the two ±15 Volt supplies, this produces
15 Watts (7.5 W plus 7.5 W) total power. The 5V output may then
deliver 5 Watts maximum (not 15W) so that the total converter
power is 7.5W+7.5W+5W=20W.
Regulation Differences Between Outputs
Looking at the Schematic diagram, observe that magnetic energy
driven from the primary side affects all three outputs simultane-
ously since they share a common transformer in combination a with
magnetically coupled output inductor. We see that the regulation
feedback is derived directly from the 5 Volt output and indirectly
from the 12/15V outputs. Increasing current on the 12/15V outputs
absorbs magnetic energy driving the 5V output therefore reduc-
ing the 5V output voltage. Regulation compensates for this drop in
output voltage but not to the same extent as the 5V output regula-
tion.
Short-circuit Conditions
Because of the interconnected regulation and common transformer,
a short circuit on one output will cause a voltage reduction on the
remaining unshorted outputs. This effect is more pronounced for
the 5V superior output vs. the 12/15V subordinate outputs. That is, a
5V short essentially places the PWM controller in power-limit mode
whereas a 12/15V short may leave some partial power available on
the remaining outputs.
Time limits on short circuits
The 5V output will tolerate 5 minutes maximum short circuit time
at +25 deg.C. For the 12/15V outputs, short ciruits must limit to 30
seconds at +25 deg.C. Failure to remove the short circuits within
these time limits may damage the converter or cause permanent
operational changes. Higher ambient temperatures require reduced
short circuit times. As long as shorts or overcurrents are removed
within these time limits, the outputs will automatically recover to
normal operation.
As a practical matter, since it is difcult to control short circuit
duration, make sure that the application is highly unlikely to cause
a short circuit or the input is disconnected by means of a circuit
breaker or fuse.
The Three Outputs are not isolated from each other
The three outputs share a common ground return which is fully
isolated from the primary input side but not between each other.
Therefore do not apply the outputs to applications which require
isolation between the 5V and 12/15V sections.
