*Test ripple and noise by “parallel cable” method. See detailed operation instructions at Testing of Power
Converter section, application notes.
Note:
1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load
unless otherwise specified.
2. Dual output models unbalanced load: ±0.5%.
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.
Recommended testing and application circuit

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. However, the capacitance of
the output filter capacitor must be proper. If the
capacitance is too big, a startup problem might

Output Voltage Regulation and Over-voltage
Protection Circuit
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).
