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.
