APPLICATIONS
Where the voltage of the input power
supply is fixed (voltage variation ≤ ±10%);
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 not
demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits, and IGBT power
device driving circuits.

minimum output load is not less than 10% of the full load, and that this product should
never be operated under no load! If the actual output power is very small, please
connect a resistor with proper resistance at the output end in parallel to increase the load,
or use our company’s products with a lower rated output power (E_S-1W&F_S-1W).
