APPLICATIONS

The IE_KS-1W&IE_S-1W Series are specially designed for applications where a group of polar p ower supplies are isolated from the input power supply in a distributed power supply system on a circuit board. These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation ≤±5%); 2) Where isolation is necessary between input and output (isolation voltage ≤3000VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

During operation, make sure the specified range of input voltage is not exceeded, the minimum output load is not less than 10% of the full load, that this product should never be operated under no load! Filtering To get an extreme low ripple, an “LC” filtering network may be connected to the input and output ends of the DC/DC converter, which may produce a more significant filtering effect. It should also be noted that the inductance a nd the frequency of the “LC” filtering network should be staggered with the DC/DC frequency to avoid mutual interference see (figure 1). Vin GND +Vo 0VDCCin L L DC L Cout Cout -Vo (Figure 1) In some circuits which are sensitive to noise and ripple, a filtering cap acitor may be added to the DC/DC output end and input end to reduce the noise and ripple. However, the capacitance of the output filter capacitor must proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provid ing the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor refer to the external capacitor table (table1).

The simplest method is to connect a self- recovery fuse in series at the input end or add a circuit breaker to the circuit. When the environment temperature is higher than 71 °C, the product output power should be less then 60% of the rated power. No parallel connection or plug and play. Use dual output simultaneously, forbid opening output pin(0V) to use as single output.
