If the actual output power is very small, please connect a resistor with resistance of 10% rated power at the output end in parallel, or use our company’s products with a lower rated output power D ual Out p ut ② Overload Protection Vin Under normal operating conditions, the output circuit of these products has no REG GND protection against overload. The simplest method is to connect a slow-blow 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 ripple or the input inrush current, an “LC” REG +Vo REG -Vo REG +Vo DC DC 0V Single Out p u t Vin REG DC DC GND 0V filtering network may be connected to the input and output ends of the DC/DC converter, (Figure 2) 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.

If the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe 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).
