These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation ≤ ±10%); 2) Where isolation is necessary between input and output (isolation voltage Note: 1. IB_XT-1W series designing; 2. IB_XT-1W series have no 3,6,8,9pin,for example IB0505XT-W75. ≤1000VDC); 3) Where the regulation of the output voltage and the output ripple noise are not demanding.

However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1).
