G_S-2WR2 & H_S-2WR2 series meets reinforced insulation requirements. They are especially designed for applications where extremely high
isolation, low insulation capacitor with low leakage current in a compact package size is required. They are widely used in applications
such as medical, electrical grid, IGBT driver circuits and similar where:
1. The voltage of the input power supply is relatively stable with a variation of ±10%Vin or less;
2. An extremely high input to output isolation voltage of up to 4200VAC or 6000VDC is required;
3. The requirement for ripple & noise or a tight output regulation is not as strict.

Design Reference
1. Typical application
Input and/or output ripple can be further reduced, by connecting a filter capacitor from the input and/or output terminals to ground as
shown in Fig.3.
Choosing suitable filter capacitor values is very important for a smooth operation of the modules, particularly to avoid start-up problems
caused by capacitor values that are too high. For recommended input and output capacitor values refer to Table 1.
For a tight output voltage regulation, including overvoltage, overcurrent and over temperature protection, we recommend the use of a
linear regulator that is connected in series to the input and/or output terminals as shown in Fig. 4.

3. Output load requirements
For a reliable and efficient operation of the converter, the minimum load should never be less than 10% of the rated output load. If the total
required output power is below 10%, a parallel bleeding resistor is required on the output, ensuring that the sum of the power consumption is
always maintained at 10% minimum.
