    Hello

    I am looking information for this 24V SMPS

    It has a rating 24V Dc, 5.0A
    so It means it can supply maximum 24V DC and 5.0A current
    I want to calculate a minimum voltage and current it can supply

    How to find minimum voltage and current it can supply to load ?

    Output voltage is 24V, that's it.
    Current drawn will depend on your circuit BUT only to a maximum of 5Amp.

    Suggest you do a bit of basic electrical 101.

    As above and from the labels on the device, it has a fixed, constant 24 V output. You can draw constantly any amount of current up to a max of 5,0 A.

    Note - if this is a switching supply, it might have a minimum output current requirement. Check the datasheet or owner's manual. many switchers require a minimum load of 10% of the rated output current. In your case that would be 0.5 A. The transformer and regulator circuit in a switching supply are very different from those in a linear supply. In particular, the transformer requires a minimum amount of energy through it to stabilize its performance.

    Does it provide a constant 5A to load?

    How much minimum current it can be drawn?

    Did you read #2?
    The output voltage is 24V DC and can be adjusted slightly by the screw.

    The minimum output current will be zero if nothing is connected:).
    The actual current (5A Max) will be what the load demands. The limit may be by a current limit circuit, a fuze or by a fire.

    No. It provides a constant 24 V to the load. This is a constant voltage power supply.
