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. 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. 24 250 48 150 U Fuse (slow-blow type) (mA) Recommended 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).

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 greatest capacitance of its filter capacitor see (Table 1).

The input current of the power supply must be sufficient to the startup current (Ip) of the DC-DC module. IS C 5. 10 ~ 100 μF Lin CTRL Terminal When open or high impedance, the converter work well; When this pin is ‘high’; the converter shutdown; It should be note that the input current should between 5~10 mA,exceeding the maximum 20 mA will cause permanence damage to the converter. The value of Vc not limited and desirable 5 Vdc, 12 Vdc, or directly with Vin. The value of R can be derived as follows: O 4.
