T1/CEPT/ISDN
Test Transformer
TEW5009
TEW5009 is specifically
designed to be used as an
isolation transformer in test
setups for testing Longitudinal
Balance and Return Loss in
Primary Rate and Basic Rate
Circuits.
Special attention has been given
to the problems associated with
the coupling capacitance
between windings when
transforming from balanced to
unbalanced circuits.
• Shield between windings.
• Very low Leakage
Inductance.
• Excellent balance.
