6.Current Sharing with Remote Sense

RSP-1600 has the built-in active current sharing function and can be connected in parallel, up to 6 units, to provide higher output power as exhibited below :

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

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

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

the current shared among units may not be balanced.

※

×

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)

output load is more than 5%.

If the lines of CN500 are too long, they should

be twisted in pairs to avoid the noise.
