The simplest method is to connect a self-recovery fuse in series at the Requirement On Output Load To ensure this module can operate efficiently and reliably, a minimum load is specified for input end or add a circuit breaker to the circuit. this kind of DC/DC converter in addition to a maximum load (nam ely full load). During No parallel connection or plug and play. 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 increase the load, or use our company’s products with a lower rated output power.
