    7 tips for using a switching power supply

    1. Confirm whether specifications of input or output voltage comply with nominal value of the power supply before use.
    2. Check whether input and output leads are correctly connected before powering on for prevention of equipment damages.
    3. Check whether various components are tightened up. Check whether there are contacts between screws and electrical parts of power panel. Measure insulation resistance between shell and input or output leads for prevention of electric shock.
    4. Make sure the ground terminal is properly connected to the ground to grantee safety and reduce noise waves.
    5. Multiplexed output refers to a power supply with primary and secondary output. The primary output performs better than secondary output. In general conditions, the one with larger current is the primary output. To ensure adjustment rate and dynamic indicators of output load, it is required to at least carry 10% of its load. If using secondary output instead of the primary one, users should exert dummy load on the primary output. Please refer to the specifications of different models for more details.
    6. To be noticed that frequent switching of power supply will have negative influence on its life span.
    7. Operating environment and on-load level will influence life span of switching power supply.
