ProgressiveRC RSP-2000 series - Manual (Page 5)

5.Current Sharing with Remote Sensing
RSP-2000 has the built-in active current sharing function and can be connected in parallel to provide higher output power :
(1)Parallel operation is available by connecting the units shown as below.
(DA,DB and GND are connected mutually in parallel).
(2)Difference of output voltages among parallel units should be less than 2%.
(3)The total output current must not exceed the value determined by the following equation.
(4)In parallel operation 4 units is the maximum, please consult the manufacturer for applications of more connecting in parallel.
(5)The power supplies should be paralleled using short and large diameter wiring and then connected to the load.
(6) Under parallel operation, the minimum output load should be greater than 5% of total output load.
(7) Under parallel operation ripple of the output voltage may be higher than the SPEC at light load condition. It will go back to normal ripple level once the
output load is more than 5%.
(8) CN502/CN504 Function pin connection
V is CN502/CN504 connected to plug pin, X is CN502/CN504 not connected to plug pin.
