2. Product Description

3. Application

    1. output load requirements

        To ensure the module can operate efficiently and reliably, the minimum output load must not be less than 10% of full load. Operation. If the actual output power is low, a resistor can be connected in parallel at the output to increase the load.

    2. Overload protection

        Under normal working conditions, the output circuit of this product has no overload protection. The easiest way to add this is to add a circuit breaker to the circuit.

    3. Recommended circuit

        If you want to further reduce the input/output ripple, you can increase the capacitance accordingly or choose a low capacitance

ESR. However, the capacity of the output filter capacitor must be appropriate. If the capacitance is too high, start-up problems may occur. For each output, to ensure safe and reliable operation, the maximum capacitance must be less than the maximum capacitive load. It is not recommended to connect any external capacitors in applications with outputs less than 0.5 watts.

    4. Output Voltage Regulation and Overvoltage Protection Circuits

        The output voltage regulator, overvoltage and overcurrent protection devices are linear regulators and capacitor filter circuits with overheat protection, which can be connected in series with input or output terminals. The recommended capacitance value of its filter capacitor, while the linear regulator is determined according to the actual required voltage and current.
