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 o Operating Temp.( C) of its filter capacitor sees (Table 1).

The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. APPLICATION NOTE Requirement On Output Load To ensure this module can operate efficiently and reliably, a minimum load is specified for this kind of DC/DC converter in addition to a maximum load (nam ely full load). During operation, make sure the specified range of input voltage is not exceeded, the minimum 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 No parallel connection or plug and play. Note: 1. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 2. Only typical models listed, other models may be different, please contact our technical person for more details. 3. Operation under minimum load will not damage the converter; However, they may not meet all specification listed. increase the load, or use our company’s products with a lower rated output power.
