OUTPUT SPECIFICATIONS
connected to the input and output ends of the DC/DC converter, see (Figure 1).
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 arise. For every channel of output, provided the safe and reliable
operation is ensured, the recommended capacitance of its filter capacitor sees (Table 1).
Output Voltage Regulation and Over-voltage Protection Circuit
is a linear voltage regulator with overheat protection that is connected to the input or output
end in series (Figure 2).
Overload Protection
No parallel connection or plug and play
Requirement on output load
output load is not less than 10% of the full load, and that this product should never be
operated under no load! 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 (E_D-1W/F_D-1W Series).
Recommended circuit
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.
