Note:
  • Ripple and noise are measured at oscilloscope 20MHz bandwidth by a 100uF electrolytic capacitor and a 0.1uF ceramic capacitor in parallel at output connector.
  • Regulation shows the percentage of absolute value of nominal output voltage.
  • Model option : C = E, E-Type (U Channel with cover)、C = U, U-Type (U Channel)
  • -1 to -20°C ambient temperature and EMS Immunity worse case O/P Regulation≦ +/-10%
  • Standby supply (V2) O/P Regulation +/-10%、Ripple and noise 150mV.
  • The switching frequency of this series is set within 58 to 75KHz at full load.
