Maximum ratings specified with rated secondary terminating
resistance and 1 turn.
Amp-µsec rating of primary equals volt-µsec rating of secondary
when secondary is terminated into rated resistance.
Maximum operatingtemperature 105⁰C.
SCALE FACTOR:
V_OUT (Volts per Amp)
1 Volt @ rated terminating resistance
