Precautions when using switching power supply
(1) Before using the power supply, first determine whether the input and output voltage specifications are consistent with the nominal value of the power supply used.
(2) Before powering on, check whether the input and output leads are connected correctly, so as not to damage the user equipment.
(3) Check whether the installation is firm, whether the installation screws are in contact with the power board components, and measure the insulation resistance of the casing and the input and output to avoid electric shock
(4) In order to ensure the safety of use and reduce interference, please ensure that the grounding terminal is reliably grounded
(5) The multi-output power supply is generally divided into main and auxiliary outputs. The main output has better characteristics than the auxiliary output. Generally, the output with the largest output current is the main output. In order to ensure the output load adjustment rate and output dynamics and other indicators, generally each channel is required to carry at least 10% load. If the auxiliary road is used instead of the main road, the main road must be properly dummy load. For details, please refer to the specifications of the corresponding models.
(6) Please note: Frequent switching of the power supply will affect its life.
(7) The working environment and the degree of loading will also affect its life.
