C.C (Constant Current) Mode of Power Supply

[Crazy8]

Hi,
what does C.C (Constant Current) mode of power supply means..when C.C mode is "ON"/Active, the power supply doesn't provide voltage any more as it stays on fixed voltage.
Can any one explain it clear.
Thanks

constant current power supply means that this supply will provide a constant current inspite of load variations. this is achieved by automatic adjusting the terminal voltage , so that the current flowing through the load becomes a constant value as R is constant for a particular load.

In my case I have connected 2 Power supplies in series (31V max of each) making 62V total Vin.
at some stage/some times while increasing the Vin after 31V, CC mode LED turns ON and Vin remains constant at 31Vin.The point 2 is marked in attached image whose CC LED turns ON.

are the two power supplies isolated with each other ?

Yes..I have connected in Independent mode.they work independently as separate units.therefore connected in series to increase the Vin to 62V..but why it shifts to CC mode, Its not clear to me.
