0 Adc.
3. Maximum volt-time product is for the secondary, based on 2000 Gauss.
4. Primary current of 20 A causes less than 25°C temperature rise from
25°C ambient. Higher current causes a greater temperature rise (see
Temperature Rise vs Current curve).
5. Terminating resistance (RT) value is based on 1 Volt output with 20 Amps
flowing through the primary. Varying terminating resistance increases or
decreases output Voltage/Ampere according to the following equation:
RT = Vout × Nsec / Iin.
