Hinweise
  1. When ordering, please specify packaging code: e.g.CST7030-150LC
  2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 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 (Ohms) = Vout × Nsec / Iin.
  6. 500 Vrms, 1 minute isolation (hipot) winding to winding.

Anschlüsse:
