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 circuit

If you want to further decrease the input/output ripple, an capacitor filtering network may be connected to the input and output ends of the DC/DC

converter, see (Figure 2).

It should also be noted that the capacitance of 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).

’s not recommended to connect any external capacitor in the application field with less than 0.5 watt output.

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 regulator and an capacitor filtering network

with overheat protection that is connected to the input or output end in series (Figure 3), the recommended capacitance of its filter capacitor sees

(Table 1), linear regulator based on the actual voltage and current to reasonable selection.

Note:

1. Operation under minimum load will not damage the converter; However, they may not meet all specification listed, and that will reduce the

life of product.

2. All specifications measured at Ta=25

°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.

3. In this datasheet, all the test methods of indications are based on corporate standards.

4. Only typical models listed, other models may be different, please contact our technical person for more details.

5. Our company offer custom products.
