APPLICATIONS

The WFB_CS-2W Series are specially designed for applicati ons where a wide range input voltage power 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 voltage range: 2:1; 2) Where isolation is necessary between input and output(Isolation Voltage≤2000VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

Generally, the capacitance is no greater than 47uF. General: Cin & Lin: 22uF & 12uH Cs: 47uF(max) Cout:100uF Recommended Circuit All the WFB_CS-2W Series have been tested according to the following recommended testing circuit before leaving factory. This series should be tested under load(Figure 1). If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance should not be too high (see Table 1).If you want to use the products in high EMI, please choose our metal packaged products. External Capacitor Table(Table 1) Vout Cout (Max) 12 330uF 15 220uF Input Current Nominal input voltage range. The input current of the power supply must be sufficient to the startup current (Ip) of the DC/DC module (Figure 2) Input Current(A) Input Voltage (V) Input Voltage Range Ip No parallel connection or plug and play.

Make sure the specified range of input voltage is not exceeded, the minimum output load no less than 10% load. If the actual load is less than the specified minimum load, the output ripple may increase sharply while its efficiency and reliability will reduce greatly. If the ac tual output power is very small, please add an appropriate resistor as extra loading, or contact our company for other lower output power products. NC terminal Unless otherwise specified, NC terminals of all se ries are used for conver ter's interior circuit connection, and are not allowed connection of any external circuit. CTRL When open or high impedance, converter work we ll.; When this pin is ’high’,the converter shutdown; Please note that the input current of this pin should between 5-10mA,exceeding the maximum 20mA will cause permanence damage to converter
