6.Current Sharing with Remote Sensing
RSP-1000 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.
(+S,-S and CS are connected mutually in parallel).
(2)Difference of output voltages among parallel units should be less than 0.2V.
(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.
(output current at parallel operation)=(Rated current per unit) (Number of unit) 0.9× ×
Note : In parallel connection, maybe only one unit (master) operate if the total output load is less than 5% of rated load condition.
The other PSUs (slaves) may go into standby mode and their output LEDs will not turn on.
