Miniature Trigger
Transformers
TR-2189/2190/2206/
2207
These transformers were custom-
designed for reliable triggering of the
PerkinElmer GP-485/486/488/489
triggered spark gaps. They have
operating circuit output voltages well
above the maximum required by the
switches and are capable of sustain-
ing the trigger to adjacent electrode
current during the turn-on phase of
gap operation. These transformers
are constructed using miniature
cores, wound and potted, to produce
high output voltage with a minimum
of corona at twice rated output volt-
age. The TR-2189 and TR-2206 are
low input voltage transformers,
round, with flying leads and solder
connections. The TR-2190 and
TR-2207 are high input voltage
transformers, square, with pins for
PC board connection.
