## **4.Current Sharing** 

MSP-1000 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 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: 

- 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.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
