APPLICATION NOTES
1. Requirement on output load
To ensure this module can operate efficiently and reliably, the minimum output load may not be less than 10% of the full load during
operation. If the actual output power is low, connect a resistor at the output end in parallel to increase the load.
2. Overload Protection
Under normal operating conditions, the output circuit of this product has no protection against overload. The simplest method to add
this is to add a circuit breaker to the circuit.
3. Recommended circuit
If you want to further decrease the input/output ripple, you can increase the capacitance accordingly or choose capacitors with low
ESR (see Figure 1). However, the capacitance of the output filter capacitor must be appropriate. If the capacitance is too high, a
startup problem might arise. For every channel of the output, to ensure safe and reliable operation, the maximum capacitance must
be less than the maximum capacitive load (see Table 1).

It’s not recommended to connect any external capacitors in applications with less than 0.5 watt output.
4. Output Voltage Regulation and Over-voltage Protection Circuit
The device for output voltage regulation, over-voltage and over-current protection is a linear regulator and a capacitor filtering network with overheat protection which can be connected to the input or output end in series (see Figure 2). The recommended capacitance of its filter capacitor (see Table 1), and the linear regulator is based on the actual voltage and current required.
