DESCRIPTION
P3127 is a high impedance transformer for
applications where high performance and safety
isolation to the most exacting international
standards are required in a compact case size.
In conjunction with external protection (e.g. fuses,
zener diodes, etc.) the device is compliant with
EN 50020 for peak rated voltage ≤375V.
P3127 has a turns ratio of 1.732:1 giving an
impedance transformation of 3:1.
P3127 is designed for “listening” applications when
placed across a line, presenting a very high
impedance to minimize circuit loading.
Signal performance is equivalent to ETAL® P1487.
