APPLICATION NOTES
1. Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, the minimum output load could not be less than 10% of
the full 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-W25&F_S-W25).
2. Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to
connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit.
3. Recommended testing and application circuit
If you want to further decrease the input/output ripple, an “LC” filtering network may be connected to the input and output ends
of the DC/DC converter, see (Figure 1). It should also be noted that the inductance and the frequency of the “LC” filtering network
should be staggered with the DC/DC frequency to avoid mutual interference. 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 recommended capacitance of its filter capacitor sees (Table 1).

4. Output Voltage Regulation and Over-voltage Protection Circuit
The simplest device for output voltage regulation, over-voltage and over-current protection is a linear voltage regulator with overheat
protection that is connected to the input or output end in series (Figure 2).
