## **Function Manual** 

## 1. Current sharing 

- (1) Parallel operation is available by connecting the units shown as below (P+,P- 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 (Output current at parallel operation)=(The rated current per unit) x (Number of unit) x 0.9. 

- (4) In parallel operation 4 units is the maximum, please consult the manufacture for other applications. 

- (5) The power supplies should be paralleled using short and large diameter wiring and then connected to the load. 

- (6) When in parallel operation, the minimum output load should be greater than 5% of total output load. 

- (Min. load >5% rated current per unit x number of unit) 

- (7) 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 & relays will not turn on. 

- (8) Some minor noise may be heard at light load condition under parallel operation. 

This is a normal phenomenon and the performance of the PSU will not be influenced.

About Novapart

Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

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.
