MEAN WELL RSP-2000-24 [5/7] Series

4.Current Sharing with Remote Sense

◎ DA,DB and GND are connected mutually in parallel.

※ Difference of output voltages among parallel units should be less than 0.2V.

※ CN502/CN504 Function pin connection

◎V is CN502/CN504 connected to plug pin, X is CN502/CN504 not connected to plug pin.

RSP-2000 has the built-in active current sharing function and can be connected in parallel, up to 4 units, to provide higher output power as exhibited below :

※ The total output current must not exceed the value determined by the following equation:

※ The power supplies should be paralleled using short and large diameter wiring and then connected to the load.

※ Under parallel operation, the minimum output load should be greater than 5% of total output load; otherwise, it is likely that only one unit operates

whereas other units may enter standby mode or their LED status indicators may not turn on.

Maximum output current at parallel operation=(Rated current per unit) (Number of unit) 0.9××

※ ×When the total output current is less than 5% of the total rated current, or say (5% of Rated current per unit) (Number of unit)

the current shared among units may not be fully balanced.
